Which plant tissue is capable of cell division?
Apical meristem, region of cells capable of division and growth in the root and shoot tips in plants. Apical meristems give rise to the primary plant body and are responsible for the extension of the roots and shoots.
Which is the most common type of ground tissue?

The almond fruit is a typical drupe; that is, it consists of a single seed surrounded by a stony endocarp which forms the shell, a fleshy mesocarp, and an outer skin or epicarp.
What cells are in a seed?
The three primary parts of a seed are the embryo, endosperm, and seed coat. The embryo is the young multicellular organism before it emerges from the seed. The endosperm is a source of stored food, consisting primarily of starches.
Which plant tissue is found in husk of coconut?
Sclerenchyma is present in the husk of coconut. Sclerenchyma is a type of simple tissue categorized under permanent tissues.
Which is capable of cell division?
meristematic cells are undifferentiated cells of the plants that can able to divide and form tissues, organs of the plant. so cells capable of division are all the cells including stem cells, meristematic cells and undifferentiated cells.
Are all cells capable of cell division?
All cell divisions, regardless of organism, are preceded by a single round of DNA replication. For simple unicellular microorganisms such as the amoeba, one cell division is equivalent to reproduction – an entire new organism is created.
What is the other name of ground tissue?
Parenchyma. Parenchyma is a versatile ground tissue that generally constitutes the “filler” tissue in soft parts of plants. It forms, among other things, the cortex (outer region) and pith (central region) of stems, the cortex of roots, the mesophyll of leaves, the pulp of fruits, and the endosperm of seeds.
What are examples of ground tissue?
Ground tissue cells include parenchyma, (photosynthesis in the leaves, and storage in the roots), collenchyma (shoot support in areas of active growth), and schlerenchyma (shoot support in areas where growth has ceased). Parenchyma are the most abundant and versatile cell type in plants.
What are the 12 tissue types?
Skeletal Muscle Tissue.
What is tissue name?
A tissue is a group of cells, in close proximity, organized to perform one or more specific functions. There are four basic tissue types defined by their morphology and function: epithelial tissue, connective tissue, muscle tissue, and nervous tissue.
Why sclerenchyma is called dead cells?
Sclerenchyma is called a dead tissue because the cells have thick lignified secondary walls, which often die when they are matured and have ceased their elongation.
How do you identify sclerenchyma?
Characters of Sclerenchyma:
- Cells are thick-walled, hard and contain little or no protoplasm.
- The cells are oval, polygonal and are of different shapes.
- The cells are dead and the nucleus is absent.
- These cells are packed closely, i.e., intercellular spaces are absent.
Why do seeds and nuts have hard covering?
question_answer Answers(9) Scelerenchyma permanent tissue and its wall is made up of lignin. Sclerenchyma is the tissue present in hard covering of seed. Lignin is responsible for making tissue hard.
As we have seen in the above discussion, Sclerenchyma is the dead and hard tissue of a plant. And we have already mentioned in the hint that husk of coconut is made up of dead cells and it is hard and stiff. So, by this we can conclude that the tissue that is present in the husk of coconut is Sclerenchyma.
Connective tissue supports other tissues and binds them together (bone, blood, and lymph tissues). Epithelial tissue provides a covering (skin, the linings of the various passages inside the body).
Which tissue is present in veins of leaves?
The walls of the veins of the leaves are made of parenchymatous cells.
Are present as covering of the seeds?
The outer covering of a seed is called the seed coat. Seed coats help protect the embryo from injury and also from drying out.
Is present in the hard coat of seeds outer covering of coconut?
Hint:The husk of coconut is the outer covering of the coconut which is brown in colour, hard, rough and made up of dead cells. Complete Answer: >Sclerenchyma:-Sclerenchyma is the dead and supporting tissue of a plant.
Which tissue is present in leaf stalk?
Collenchyma
Collenchyma is a specialized supporting tissue. It consists of elongated cells with non-uniformly thickened wall. This tissue possesses considerable tensile strength and is found in stems and leaves. It provides support to the stalk of a leaf.
What is the outer covering of the seed known as?
An endosperm stores food and provides nutrition to the plant in the form of starch. It is formed during the process of double fertilization. What is the outer covering of the seed known as? The outer covering of the seed is known as a seed coat.
What are the parts of a seed plant?
An embryo contains the underdeveloped tissues of leaves, stem, and roots of a plant. What are the Parts of an Embryo of a Seed Epicotyl – The tiny shoot of an embryo, from which the entire shoot system develops. The tip of the epicotyl is called plumule.
Why does a seed have a thick coat?
A thick seed coat protects the seed from sunlight and water. It prevents the loss of water and entry of parasites within the seeds. The hard seed coats prevent germination during unfavourable environmental conditions. An opening in the integument of the ovule known as the micropyle is visible on some seed coats.
Where does the seed coat of the ovule come from?
The seed coat forms from the two integuments or outer layers of cells of the ovule, which derive from tissue from the mother plant, the inner integument forms the tegmen and the outer forms the testa.
What is the outer layer of a seed called?
They are the protective outer covering of a seed, usually hard, thick, brownish in color, and not permeable to water. The seed coat is formed from the outer covering of the ovule called the integument. It usually contains two layers: i) the outer thicker layer called testa, and ii) the delicate inner layer called tegmen.
An embryo contains the underdeveloped tissues of leaves, stem, and roots of a plant. What are the Parts of an Embryo of a Seed Epicotyl – The tiny shoot of an embryo, from which the entire shoot system develops. The tip of the epicotyl is called plumule.

Where are meristematic tissues found in a plant?
(c) Meristematic tissues consists of actively dividing cells and is present in the growing regions of plants, e.g., the tips of roots and stems. The cells of meristematic tissue are round, oval, polygonal or rectangular.
