TEKS: 3.13B Life Cycles

Insect Life Cycle

• egg, larva, pupa, adult

• egg, nymph, pupa, adult

• egg, larva, adult, cocoon

• egg, larva, chrysalis, juvenile

Seedling

• A fully grown plant ready to bear fruit.

• A baby plant that has grown from a seed and is still very small.

• A type of seed that has not yet germinated.

• A plant that has just started to wilt.

Nymph

• Immature form of some insects such as a dragonfly. They resemble the adult, but are smaller.

• A type of aquatic plant found in ponds.

• A stage in the life cycle of amphibians like frogs.

• A mythical creature often depicted as a beautiful maiden.

Complete Metamorphosis

• The body of an organism completely changes in shape and appearance at each stage of its life cycle (e.g., Butterflies).

• The organism undergoes minor changes in shape and appearance throughout its life cycle.

• The organism remains the same in shape and appearance throughout its life cycle.

• The organism changes color but not shape during its life cycle.

Germinate

• Process in which a plant begins to sprout or grow.

• A method of planting seeds in water.

• The stage when a plant produces flowers.

• The process of drying out seeds before planting.

Plant Life Cycle

• Seed, germination, reproduction, pollination, and seed spreading stage.

• Photosynthesis, respiration, and transpiration stages.

• Growth, dormancy, and decay stages.

• Fertilization, growth, and harvesting stages.

Life Cycle

• A series of stages a living thing goes through during its life.

• A process of reproduction in plants only.

• The stages of development in a non-living object.

• A method of measuring time in biology.

Incomplete Metamorphosis

• The young undergo significant changes in body structure as they grow.

• The young grow and develop through time to become adult-size, but their outward body appearance does not change substantially (e.g., Grasshoppers).

• The young transform into a completely different organism during their life cycle.

• The young remain in a larval stage throughout their entire life.
