Required Answers:-
1) The chloroplasts containing chlorophyll that gives green colour is converted to chromoplasts that secretes lycopene. Lycopene gives red appearance to tomato.
2) No change in the plant cell since there is the cell wall that balances the turgor pressure developed due to osmosis. The RBC will burst because of no cell wall.
3) Cuticle (Helps in preventing excess loss of water during transpiration).
4) Keratinized stratified epithelial tissue.
5) Basement membrane. (The acellular layer between the epithelial tissue and connective tissue).
6) Ligament (a dense regular connective tissue).
7) Smooth muscles (Involuntary muscles).
8) Cardiac muscle (Involuntary)
9) Skeletal muscles (Voluntary)
10) Nervous tissue
11) Neurons (nerve cells) and neuroglia.
12) Axon
13) Adipose tissue (loose connective tissue).
14) Catilage and bones (specialized C.T.)
15) Chondrocytes and osteocytes respectively.
16) Calcium and phosphorus. (calcium phosphate).
17) On the epidermis. (lower surface of leaf in majority of the plants and in the upper surface in aquatic plants).
18) Ciliated epithelial cells.
19) Elastic cartilage.
20) In the attachment.
21) Tendons
22) Areolar tissue (loose C.T.)
23) Properties of meristematic tissue are:
- Ability to divide.
- Living and thin walled cells.
- Absence of intercellular spaces.
- Rich in protoplasm.
24) Types of meristematic tissues according to position: Apical meristem, Intercalary and lateral meristem.
25) Ciliated epithelium or Brush bordered epithelium.
Answer:
REQUIRED ANSWER:
