Botany Questions- Ch. 1

Front 1

Which description(s) pertains to the cell type of plants?

Back 1

-multicellular
-eukaryotic

All plants are multicellular (“many celled”) eukaryotes, which distinguishes them from bacteria (single-celled prokaryotes) and algae (single-celled or multicellular eukaryotes).

Front 2

Which description(s) pertains to the cell structure of plants?

Back 2

-cell wall(mostly cellulose)

Plant cells have cell walls, which distinguishes them from animal cells (no cell walls).

The cell walls of all plants are composed mainly of cellulose. Although the cells of bacteria and fungi also have cell walls, they are not composed mainly of cellulose.

Front 3

Which description(s) pertains to the mode of nutrition of plants?

Back 3

-autotrophic
-photosynthetic

Almost all plants are photosynthetic autotrophs – that is, they make their own food through photosynthesis. This characteristic distinguishes plants from animals and fungi, which are both heterotrophs.

Front 4

Which description(s) pertains to the reproduction of plants?

Back 4

-2 adult forms
-sexual reproduction
-asexual reproduction
-production of spores
-production of eggs/sperm
-protected embryo

Plants have two adult forms, either separate or attached, that alternate in producing each other. One adult form produces spores through asexual reproduction. The other adult form produces eggs and sperm through sexual reproduction. A sperm fertilizes an egg to produce an embryo, which is protected within the mother plant.

Although algae and fungi also reproduce sexually and asexually, they do not develop from an embryo. Although animals develop from an embryo, most only reproduce sexually.

Front 5

Which description(s) pertains to the growth of plants?

Back 5

-indeterminate growth
-determinate growth

Plants may exhibit indeterminate growth or determinate growth. This characteristic distinguishes plants from animals, which only exhibit determinate growth.
