cells

true or false

eukaryotes have membrane bound organelles

smallest units of life

cell

3 parts of cell theory

basic units of life... make up all organisms...all come from previous existing cells

cells want to have a larger "blank" than "blank"

surface area, volume

explain the significance of the cell theory and what it tells us about life today.

we all have came from one cell since we have come from preexisting cells which means we all have one of the same ancestor

explain why cells divide to remain small and do not grow to huge sizes.

cells want to remain small to regulate processes in the cell

eukaryotes.

large and complex, 2.5 Million years old, made of multiple cells

prokaryotes.

small and simple, single celled, lacks a nucleas

pro and euk

cell wall, flagella, include organelles

nucleas

controls cell and holds DNA

nucleolus

produces ribosomes

rough er

proteins are produced

mitochondria

gives off energy and breaks down glucose

vacoule

stores food and water

lysosomes

breakdown unwanted particles only in animal

smooth er

produces lipids

golgi appartus

packages and sorts proteins and lipids

centrioles

aids in cell division only in animal

cytoplasm

makes a home for cell organelles

cell membrane

controls what goes in and out of cell

cell wall

supports,shapes, and protects the cell only in plant

chloroplasts

captures light energy for photosynthesis

vesicle

temporary storage of cell material

ribosomez

roaming in cytoplasm

liver cell consists of..

smooth er because it detoxifies unwanted substances

leaf cell consist of...

chloroplast to use as photosythesis
