Life Science Part 1

A teacher showed her students a picture of a tree that does not lose all its leaves every year.

How should the tree be classified?

• non-flowering

• deciduous

• coniferous

• flowering

Heredity

• The process of natural selection

• The passing of traits from parent(s) to offspring

• The study of genes and DNA

• The variation of traits within a population

Plants that reproduce using spores.

• Non-Seed Producers

• Seed Producers

• Flowering Plants

• Fruit-Bearing Plants

gymnosperms

• Non-flowering plants that keep their seeds visible, usually in a cone

• Flowering plants that produce seeds in fruits

• Plants that reproduce using spores

• Aquatic plants that have submerged roots

Plants

• organisms that produce (make) their own food

• organisms that consume other organisms for energy

• organisms that decompose organic material

• organisms that rely on sunlight for growth

What is the function of the nucleus in both animal and plant cells?

• It produces energy for the cell.

• It controls the activities of the cell.

• It stores genetic information.

• It helps in the synthesis of proteins.

A living thing; organisms are capable of growth, reproduction, and responding to their surroundings.

• Organism

• Cell

• Tissue

• Species

Vascular Plants

• grasses and fruit trees

• mosses and ferns

• algae and lichens

• cacti and succulents

Complex multicellular organisms that consume other organisms for food; examples are mammals, fish, birds, amphibians, reptiles, and insects

• Plants

• Fungi

• Animals

• Bacteria

The jelly-like substance that fills cells and holds organelles in place.

• Cytoplasm

• Nucleus
