Questions and Answers

What are the three main parts of a seed?

Division, elongation, and maturation

Seed coat, endosperm, and embryo (correct)

Radicle, hypocotyl, and plumule

Primary growth, secondary growth, and vascular cambium

What is the difference between primary and secondary growth?

Primary growth is horizontal growth at lateral meristems, whereas secondary growth is vertical growth at apical meristems.

Primary growth occurs before secondary growth, whereas secondary growth occurs before primary growth.

Primary growth is the sprouting of a seedling when environmental conditions are favorable, whereas secondary growth is the production of cork, the outermost protective layer.

Primary growth is vertical growth at apical meristems, occurring before secondary growth, whereas secondary growth is horizontal growth at lateral meristems, only occurring in woody plants. (correct)

What is the function of the vascular cambium?

To produce water for seed germination and growth.

To produce cork, the outermost protective layer.

To produce secondary xylem and phloem, forming growth rings. (correct)

To provide a protective layer for the seed

Study Notes

A seed has three main parts: seed coat, endosperm, and embryo.
The embryo has four parts: radicle, hypocotyl, plumule, and epicotyl.
Germination is the sprouting of a seedling when environmental conditions are favorable.
Primary growth is vertical growth at apical meristems, occurring before secondary growth.
Root growth has three zones: division, elongation, and maturation.
Secondary growth is horizontal growth at lateral meristems, only occurring in woody plants.
Vascular cambium produces secondary xylem and phloem, forming growth rings.
New xylem is produced every year, whereas new phloem replaces old phloem.
Cork cambium produces cork, the outermost protective layer.
Water is essential for seed germination and growth.
