The kind of tissues present at the stem tip of a flowering plant.
The kind of tissues present at the stem tip of a flowering plant.
Ans: – Meristematic tissue present at the stem tip of a flowering plant.
The tissue which connects muscle to the bone.
Ans: – Fibrous tissue connect muscle to the bone.
The kind of tissue which forms the inner lining of blood vessels.
Ans: – The inner lining of blood vessels is the unstriped tissue.
Undifferentiated cells which can divide through mitosis and differentiate into specialized cell types.
Ans: – The stem cell divided the mitosis and differentiate into specialized cell types.
Name the kind of plant tissue found
at the growing parts of the plant.
Ans: – Meristematic tissue.
at the root tip.
Ans: – Apical meristem.
in vascular bundles.
Ans: – Xylem and phloem.
in the inner lining of the intestine.
Ans: – Epithelial
Connecting the adjacent muscle fibres.
Ans: – Tendons.
State one point of difference between the following (one key difference only).
Cytoplasm and protoplasm.
Ans: – Protoplasm has nucleus but cytoplasm not.
Cell wall and cell membrane.
Ans: – cell membrane is present in plant and animal cell and cell wall is present in plant cell only
Ribosomes and mitochondria.
Ans: – Ribosomes helps in protein synthesis and mitochondria helps in providing power in cell.
Blood and lymph.
Ans: – The body temperature is controlled by the blood whereas the body works against the pathogens by the helps of the lymph.
Cell and tissue.
Ans: – The fundamental unit of body is known as the cell and this group of cells made a tissue.
Cartilage and bone.
Ans: – Bone is hard whereas cartilage isnot like that its soft.
Meristematic tissue and permanent tissue.
Ans: – Permanent tissue doesn’t helps in growth but meristematic does.
Which cell organelle is responsible for the release of energy in the form of ATP?
Ans: – Mitochondria is responsible for the release of energy in the cell in ATP form.
What is the significance of cell membrane?
Ans: – The outer cover of the cell of plant and animal is known as the cell membrane. The cell membrane protects the cell inner side.
Why are mitochondria known as the ‘powerhouse’ of the cell?
Ans: – As the mitochondria provides the energy to every organ of the cell this mitochondrion is known as the powerhouse of the cell.
What will happen to a cell if its nucleus is removed?
Ans: – The whole body or the cell are controllable by the nucleus so when it will remove the cell doesn’t work properly or damage.
Is this statement true or false: Plant cells have chloroplasts, but no mitochondria? Justify your answer.
Ans: – The works of mitochondria is to provide the energy to the cell in the plant body whereas the chloroplast also makes the energy for the different plant cell.
Mention three features found only in plant cells and one found only in animal cells.
Ans: – Chloroplasts, cell wall, globoids only present in plant cell. And in plant cell lysosome present.
Name three kinds of permanent tissues found in plants. Write one function of each.
Ans: – The three kinds of permanent tissue are –
- Parenchyma
- Collenchyma
- Scremchyma
What is a protective tissue? Why is epidermis considered as a protective tissue?
Ans: – The protective cell is the cell which present in the outermost part of the cell body. This protective cell protects the cell from the outer affect and this cell protection tissue is cell wall and cell membrane.
What is stem cell technology? Give its two uses in disease control.
Ans: – The different types of bone marrow disease and the blood cancer is treated by this technology which is cell technology. This technology helps in the control of blood base disease control of the body.
Given below is an incomplete table relating to certain structures found in animal/ plant cell, their location and function. Study the table and then give the appropriate answer in terms of structure, location and function for the blanks numbered from 1 to 9.
Ans: –
| Structure | Location | Function |
| plant | Plant cell | Photosynthesis |
| mitosis | Animal cell | Spindle formation during cell division |
| cell wall | Plant cell | Protection |
| Cell membrane | Plant cell | Selectively permeable membrane |
| nucleus | Plant cell | Control the whole cell |
