Life Semester 1 Review

Captures energy from sunlight and changes it to energy

One Cell

Cytoplasm Divides

Changes in an organisms environment that causes them to react

When 2 or more elements combine

First stage of the cell cycle

Theory involving living things coming from nonliving things

Scientific study of how organisms are classified

Process of grouping things based off of similarities

Basic Unit of Structure and Function

A group of tissues working together

Breaks down larger food particles into smaller ones

green pigment for photosynthesis

Process by which cells obtain energy from glucose

Control center of the cell

Network of membranes that produces many substances

Science carries out a series of tests that are identical except for one factor

A trait that's passed on

Stores water, food and waste in a cell

Chemical reactions that builds up or breaks down materials

A group of cells working together

Two name naming system

Produces proteins

Process of change over time

Instruments that make things look bigger

carbon, oxygen, hydrogen, nitrogen and phosphorus

Energy releasing process that does not require energy

Classification grouping that contains similar closely related organisms

Living Things

Rigid layer that surrounds a cell

Reproduction involving 1 parent

Carbon, hydrogen, oxygen and nitrogen

Series or events in which an organism eats another to obtain energy

carbon, hydrogen and some oxygen

Cells have a nucleus

Multiple Cells

Process of change that occurs during an organisms life

genetic material that carries information about an organism

A substance that can not be broken down into a simpler substance

A group of organs working together

Cant make its own food

Unrelated organisms evolve characteristics that are similar

Unicellular organisms that lack a nucleus

Cell makes an exact copy of the DNA in its nucleus

Model showing how matter and energy are transferred among organisms

DNA and proteins form threadlike structures

The cells nucleus divides into two new nuclei

carbon, oxygen and hydrogen

Powerhouse of the cell

Shows probable evolutionary relationships among organisms

Group of similar organisms that can mate and have offspring

Speed up chemical reactions

cells capture energy in sunlight and use it to make food

Controls which substances come into and out of a cell

An action or change in behavior

Shape of DNA

Reproduction involving 2 parents

Receives and packages proteins and sends them to other parts of the cell

Widely accepted explanation of the relationship between cells and living things

Maintaining stable internal conditions

Regular sequence of growth and division

Makes its own food

Tiny cell structures

Fills region between cell membrane and the nucleus
