D. comsume pollen and eggs
Gametophytes
A. consume spores
B. generate spores
C. generate pollen and eggs
D. comsume pollen and eggs
Flowers are
A. sporphytes
B. gametophyes
C. non-vascular
Explanation / Answer
Answer:
1). B. Flowers
Explanation: Flowers are produced in angiosperms only.
2). C. Cones
Explanation: Cones are produced in gymnosperms only.
3). B. Non-vascular
Explanation:
.Non-Vascular plantscannot grow very tall and because of their small sizes they can absorb enough water to carry materials throughout the plant.
4). A. Circulation
Explanation: Water carries nutrients and minerals and transport throughout the plants.
5). C. Cambium
Explanation:
Cambium is a meristematic tissue. It divides continuously and helps in growth of the plant body.
6). A. Xylem
Explanation: Xylem transports water (H2O) and phloem transports food material (glucose).
7). A. Xylem
8). A. Active transport
Explanation: Phloem loading the process whereby carbohydrates enter the sieve tubes at the source, as a result of phloem loading, a high concentration of sugar develops in phloem cells near the sources. requires active transport of ATP
9). D. Bacteria
Explanation: Plant fix nitrogen by bacteria (symbiotic bacteria)
