A.G - Biology Collection 2

1. Herbaceous Stem

An herbaceous stem is the stem of plant that dies down to its roots every year during cold climates. In warmer climates an herbaceous stem may grow all year. This plant stem is herbaceous because it contains no woody tissue.

2. Fruit - Fleshy with Seed


A fleshy fruit with seeds has a fleshy fruit that protects the seeds that create new trees. The fruit is the matured ovary of the pistil of a flower. This apple is a fleshy fruit with seeds inside.

3. Bryophyte


Bryophytes are non-vascular plants that have tissues, an enclosed reproductive system, and reproduce through spores. The moss on the side of this tree is an example of bryophyte.

4. Keratin

 Keratin is a family of hard, structural, tough, and insoluble proteins that form hard structures in many kinds of animals. Hair is an example of keratin.

5. Amniotic Egg


Reptiles were the first to develop amniotic eggs. These eggs were shelled, meaning that unlike the shell-less eggs of their predecessors, amphibians, they could be laid away from water. These eggs are an evolutionary advantage for reptiles, egglaying mammals and birds. This chicken egg is amniotic.

6. Long-day Plant


This clover is an example of a long-day plant. A clover is a long-day plant because it requires less than 18 hours of darkness in every 24 hours to cause flowering.

7. Epithelial Tissue 

Epithelial tissue covers the whole surface of the body. It is made up of cells closely packed and ranged in one or more layers.Epithelial tissue that occurs on surfaces on the interior of the body is known as endothelium. The skin on our hands is an example of Epithelial Tissue.

10. Adaptation of a plant

Plants have adaptations to help them survive (live and grow) in different areas. Adaptations are special features that allow a plant or animal to live in a particular place or habitat. This plant is able to grow and survive because of it's adaptation to the surrounding area.
