rough er has ribosomes on the surface while smooth er does not.
Rough ER is connected to the ---membrane and to ---ER.
nuclear and smooth
Proteins made by rough ER travel to the Golgi in sacks called ---. Golgi --- and ---proteins for export out of the cell.
cistern, modify, packages
What are Smooth ER jobs?
Make proteins, controls calcium level, detoxifies poisons.
What process takes place inside chloroplasts?
photosynthesis
What is the energy for photosynthesis?
Sun

chlorophyll
Chloroplasts are found in what type of cell(s)?
plant cells
Both chloroplasts and mitochondria are alike in that they both have ---membrane and their own--
double and DNA
Food, water, and wastes are stored inside
Vacuoles
Digestion takes place inside---containing---
lysosomes and digestive enzymes

What organelle breaks down and recyles worn out cells?
lysosomes
Cell membrane: Plant/animal/both
Both
Cell membrane - Function
Provides a boundary between the cell and its environment. Controls what enters/exits cell. Provides protection/support for cell.
cell wall - Function
Surrounds the cell membrane and its contents- give the plant its shape
cytoplasm - Plant/animal/both
both
cytoplasm - Function
Watery cell fluid that contains the cell organelles-many life processes take place here
vacuole - Plant/animal/both
both
vacuole - Function
Store water, wastes, and food. Much bigger in plant than animal cells.
ribosome - Plant/animal/both
both
ribosome - Function
Make proteins
Golgi bodies- Plant/animal/both
both
Golgi bodies - Function
Synthesize, package, and secrete cell products
rough ER - Plant/animal/both
both
smooth ER - Plant/animal/both
both
smooth ER - Function
Makes proteins and lipids that will be exported by the cell, controls calcium level and detoxifies poisons & drugs
central vacuole - Plant/animal/both
plant
central vacuole - Function
Takes up most of the space in plant cells. Store water, wastes, and food
chloroplast - Plant/animal/both
plant
chloroplast - Function
Involved in manufacturing of food (photosynthesis)
mitochondria -Plant/animal/both
both
mitochondria - Function
Convert energy stored in glucose into ATP
nucleus -Plant/animal/both
both
nucleus - Function
Control cell activities
nucleolus -Plant/animal/both
both
nucleolus - Function
Makes ribosomes
nuclear membrane -Plant/animal/both
both
nuclear membrane - Function
Materials move from the nucleus to the cytoplasm through nuclear pores in the nuclear membrane
centrosome - Plant/animal/both
animal
centrosome - Function
Makes microtubules, important for cell division
lysosomes - Plant/animal/both
animal
lysosomes -function
Contain digestive enzymes, breaks down & recycle worn out cells
microtubules - Plant/animal/both
animal
microtubules -function
Give the nucleus and cell its shape
nuclear pores -Plant/animal/both
both
nuclear pores -function
Allows materials to move through nucleus and cytoplasm

Passive transport
The cell does not use energy. High to low concentration. types - 1.Diffusion , 2.Facilitated diffusion, 3. Exocytosis
Active transport
The cell uses energy. Low to high concentration. types - 1. Protein pumps, 2. Endocytosis, 3. Exocytosis
Osmosis
diffusion of water through a selectively permeable membrane
•Phagocytosis-
cytoplasm of cell surrounds and engulfs large
•Pinocytosis-
plasma membrane "pinches in" to permit entry of molecules too large to diffuse through
Semi-permeable membrane (selectively permeable)
-allows some molecules to pass but not others
Isotonic:
The concentration of solutes in the solution is equal to the concentration of solutes inside the cell.
