Phototropic curvature in Avena coleoptile is the result of uneven distribution of
1 auxin
2 starch
3 gibberellins
4 phytochrome
Explanation:
A Phototropic curvature in Avena coleoptile is the result of uneven distribution of auxin. Auxin is a plant hormone which is responsible for cell multiplication and photoactive movement so, Auxin can effect phototropic curvature. Gibberllins- It is a group of plant hormones that collect elongation of the stem, flowering and germination. Phytochrome- It is used to detect light. It is sensitive to light in the red and far-red region of the visible spectrum. Starch:- Starch is the major reserve food material found inside the plants.

Which part of embryo comes out first during seed germination?
1 Radicle
2 Plumule
3 Hypocotyl
4 Epicotyl
Explanation:
A Radicle part of embryo comes out first during seed germination. Embryo is a miniature version of the plants. Plumule- It helps in developing the shoot system, which includes the stem, leaves, flowers and fruits. Hypocotyl- It is a part of plant seeding that lies between the radicle and the cotyledons. Epicotyl-It is a region of the stem of embryo plant found beneath the stalk of leaves directly above the root.

In germinating seeds, fatty acids are degraded exclusively in the
1 proplastids
2 glyoxysomes
3 peroxisomes
4 mitochondria
Explanation:
B In germinating seeds, fatty acids are degraded exclusively in the glyoxysomes. Glyoxysomes are small spherical vesicles enclosed by a single unit membrane. Glyoxysomes happen only in fat-rich plant cells, where they take part in $\beta$-oxidation of fats and perform the glyoxylate cycle. Proplastids- They are a pigment. They contain double membrane-bound organelle. Peroxisomes- They are small in size and their membrane is enclosed that contain enzyme involve in different metabolic reaction. Mitochondria - Mitochondria are membrane bound cell organelles that generate most of the chemical energy needed to power the cell's biochemical reaction.
