Question

Name the three main types of cell wall structure:

a) Primary, secondary, tertiary
b) Prokaryotic, eukaryotic, archaeal
c) Parenchyma, collenchyma, sclerenchyma
d) Endodermis, pericycle, epidermis

Answer 1

The three main types of cell wall structures in plants are primary, secondary, and tertiary. Cell walls provide support and shape to the cell, with bacterial cell walls being composed of peptidoglycan and plant cell walls primarily of cellulose.

Step-by-step explanation:

The three main types of cell wall structures in plants are a) Primary, secondary, tertiary. These cell walls vary in composition and structure:

• The primary cell wall is mostly made up of cellulose and is formed during cell growth.
• The secondary cell wall, found in some cells after they've stopped growing, is a thickened layer that adds strength and rigidity.
• The tertiary cell wall, when present, is found innermost and has a unique structure that differs from the other two.

All cells are surrounded by a plasma membrane. The cell wall is an additional structure found in prokaryotic, algal, fungal, and plant cells, providing support and shape. In bacterial prokaryotic cells, the cell wall is composed of peptidoglycan, while in plant cells, cellulose is a major component.
