6.1 Plant Cells and Tissues – The Science of Plants

A tissue is a group of cells that share a function. The cells within a tissue may differ from one another, but they all contribute to a particular function. We''re going to look at three types of tissues: dermal, cortex, and vascular. Dermal tissue Dermal tissues (derma is Greek for "skin") are on the outside of the plant and provide protection for the plant cells they surround.

Cell Wall

Cell Wall Definition A cell wall is an outer layer surrounding certain cells that is outside of the cell membrane. All cells have cell membranes, but generally only plants, fungi, algae, most bacteria, and archaea have cells with cell walls. The cell wall provides strength

Central Vacuole

A is correct. Vacuoles are found inside the cells of plants, fungi, and some protists, bacteria, and animals, but only plant cells have a central vacuole. One of the plant cell''s distinguishing characteristics is its large central vacuole, which can take up 30-90% of the

• Plant cells have cell walls composed of cellulose, hemicelluloses, and pectin and constructed outside the cell membrane. Their composition contrasts with the cell walls of fungi, which are made of chitin, of bacteria, which are made of peptidoglycan and of archaea, which are made of pseudopeptidoglycan. In many cases lignin or suberin are secreted by the protoplast as secondary wall layers inside the primary cell wall. Cutin is secreted outside the primary cell wall and into the
