Non-vascular plants excrete excess gases produced by cellular respiration and photosynthesis through diffusion, the movement of molecules from a concentrated area to an area of low concentration. Mosses and algae excrete... More »

There are many types of nonvascular plants, including mosses, lichens, liverworts, hornworts and algae. Algae can be further divided into three separate phylum: Chlorophyta or green algae, Rhodophyta or red algae, and Ph... More »

The primary examples of non-seed vascular plants are ferns and horsetails. They possess vascular tissue that is efficient at carrying water and enables them to grow larger than non-vascular plants. They reproduce and spr... More »

Diffusion is the spontaneous movement of any type of particle or molecule from an area of high concentration to an area of low concentration, while osmosis is the diffusion of water across a semi-permeable membrane. Osmo... More »

The relationship between photosynthesis and cellular respiration is such that the products of one process are the reactants of the other. Photosynthesis is the process whereby carbon dioxide and water react, using energy... More »

The spongy layer of a leaf features small air spaces between cells that allow for the exchange of gases in photosynthesis. Together with the palisade, the spongy layer makes up the mesophyll of the leaf. More »

Glucose, the primary product of photosynthesis, is a sugar formed from carbon dioxide and water molecules that acts as the primary food source for green plants. A secondary product of the process, oxygen, is released int... More »
