10 th Std Science one word Question & Answers
UNIT 12 - PLANT ANATOMY AND PLANT PHYSIOLOGY
1. Nehemiah
Grew is known as father of Plant Anatomy.
2. Plant
tissues can be broadly classified into Meristamatic, Permanent tissue.
3. Cuticle
is present on the outer wall of epidermis to check evaporation of water.
4. Vascular
tissue system is consists of xylem and phloem tissues.
5. Xylem
conducts water and minerals to different parts of the plant.
6. Phloem
conducts food materials to different parts of the plant.
1. Cortex
is a multilayered large zone made of thin walled parenchymatous cells with
intercellular spaces.
2. Endodermis
is the innermost layer of cortex.
3. The
tissue present between xylem and phloem is called conjunctive tissue.
4. The
large central parenchymatous zone with intercellular spaces is called pith.
5. Each
vascular bundles is surrounded by few layer of sclerenchyma cells called bundle
sheath.
6. The
tissue present between the upper and lower epidermis is called mesophyll.
7. Chloroplasts
re green plastids containing green pigment called chlorophyll.
8. Light
dependent photosynthesis was discovered by Robin Hill (1939).
9. Melvin
Calvin, an American biochemist discovered chemical pathway for
photosynthesis.
10. The
mitochondria were first discovered by Kolliker in 1857.
11. The
mitochondrion is referred to as the “power house of the cell.”
12. Carparian
strips are present in the endodermis of the root.
13. The
endarch condition is the characteristic feature of stem.
14. The
xylem and phloem arranged side by side on same radius is called conjoint.
15. Ethyl
alcohol is formed during anaerobic respiration.
16. Krebs’s
cycle takes place in mitochondrial matrix.
17. Cortex
lies between epiblema and endodermis.
18. Xylem
and phloem occurring on the same radius constitute a vascular bundle called
conjoint bundle.
19. Glycolysis
takes place in Aerobic respiration.
20. Mitochondria
is ATP factory of the cells.
