Life Science - Unit 6

Amoeba

Protist that acts as a microscopic predator in soil

Bacteria

Prokaryotic organisms that grow in colonies

Bioluminescence

Natural glowing

Cellulose

The starch that makes up plant cell walls

Chitin

The starch that makes up fungi cell walls

Chlorophyll

Green pigment in chloroplasts that absorbs light energy

Chloroplasts

Organelle where photosynthesis takes place

Cuticle

Waxy layer on plant leaves that regulate water

Decomposition

The breaking down of organic material

Diatom

Single-celled plankton with etched cell walls

Dormancy

A stage where seed embryos are alive but they are not actively growing

Flagella

Whip-like structure that allows for movement

Hyphae

Hair-like strands one cell thick that make up fungi

Mycelium

Main body of fungus that is a tangled mass of hyphae

Natural resource

Part of the environment that is useful for an organism to survive

Pathogen

Harmful invader

Pericarp

Fruit

Photosynthesis

The chemical process in leaves which absorbs sunlight and produces nutrients for the plant to use

Pioneer Species

The first species to move into a place after a disaster

Pollinator

An organism that carries pollen to fertilize plants in the process of pollination

Pollutant

Any substance that contaminates the environment

Protist

Eukaryotic organism in kingdom Protista that doesn't nicely fit into another group

Rhizoids

Thin thread-like structures in place of roots in nonvascular plants which anchor them in place but do not absorb nutrients

Stomata

Plant cell pores which allow gases to pass into or out of the plant

Tropism

Plant growth towards or away from a stimuli
