Cells-The Units of Life

�Smallest organisms on Earth �Made up of only one cell �Sentence: �Bacteria are 1 celled organisms.

�Flexible structure that holds a cell together �Boundary between cell & its environment �Helps control what enters & exits the cell �“gate keeper” of cell

� Sentence: �A cell’s membrane is its “gatekeeper”

�Found in structure of plants, algae, fungi, & many bacteria types �Supports & protects cell membrane � Sentence: � Plants have a rigid cell wall.

�Gelatin like substance inside cell membrane �Contains water, chemicals, and cell parts (organelles) �Where cell’s activities take place

�Specialized cell parts that move around in a cell �Perform jobs necessary for cell to live

�Cell organelle that contains hereditary material (DNA in chromosomes) �Directs most of cell’s activities �“cell boss”

�Balloon like cell organelle �Can store food, water, & other substances �“cell closet”

� Provides usable energy for the cell � Where process of cellular respiration takes place � “cell powerhouse”

�Process plants, algae, and many bacteria use to make food

�Green organelle in a plant’s leaf �Where photosynthesis occurs �“cell kitchen”

�Groups of similar cells that all do the same work

�Structure made of 2 or more types of different tissue �Work together to do a certain job

�Group of organs that work together to perform a certain job
