Practice question 1
The cambium, as a plant tissue, mainly functions to
- A.produce new xylem and phloem cells for growth in thickness
- B.directly carry out photosynthesis
- C.absorb water directly from the soil
- D.facilitate pollination between flowers
Show the answer
A. produce new xylem and phloem cells for growth in thickness
Cambium is the growth tissue responsible for a stem's increase in girth.
Practice question 2
A dicot plant is mainly characterized by
- A.having one cotyledon in its seed and parallel-veined leaves
- B.having two cotyledons in its seed and net-veined leaves
- C.having no root system at all
- D.having no flowers at any stage
Show the answer
B. having two cotyledons in its seed and net-veined leaves
Two cotyledons and net-veined leaves define dicots, like beans.
Practice question 3
The cotyledon, within a seed, mainly functions to
- A.protect the seed as its hard outer covering
- B.provide an initial food reserve for the developing embryo
- C.facilitate the seed's dispersal by wind or animals
- D.anchor the mature plant firmly into the soil
Show the answer
B. provide an initial food reserve for the developing embryo
Cotyledons supply the young embryo with nutrition during early development.
