Plant Development quiz Flashcards

The two cells are called the apical cell and the basal cell.

The basal cell forms the suspensor, which contributes to the supportive structures of the embryo.

The shoot apical meristem gives rise to organs like flowers and leaves.

Cotyledons are embryonic leaves in the developing plant embryo.

The root apical meristem gives rise to the roots of the plant.

The three embryonic tissues are the epidermis, ground tissue, and vascular tissue.

The epidermis is the outermost layer of cells specialized to protect the organism.

Ground tissue differentiates into specialized cells like photosynthetic cells.

Xylem and phloem are types of vascular tissues that arise from the vascular tissue.

The hormone auxin provides positional information in developing plants.

Unlike animal cells, some plant cells can dedifferentiate to become different types of cells.

This ability allows humans to cultivate plants from clippings, as plant cells can become different types of cells.

The hypocotyl is the embryonic stem of the developing plant.

The meristem contains plant stem cells that can give rise to various structures like roots, leaves, and new stalks.

The suspensor contributes to the supportive structures of the embryo, similar to the placenta in mammals.

Secondary growth never occurs in herbaceous plants. These plants do not develop the woody tissues that are characteristic of secondary growth, which is more common in woody plants like trees and shrubs.

Polyploidy is a better explanation for how chromosomes were added in plants, rather than in animals. This process involves the duplication of the entire set of chromosomes, which is more common in plants and can lead to increased genetic diversity and adaptation.
