Cell Transport
Osmosis or diffusion?
The movement of molecules from high to low concentrations without the use of energy. ex) sugar
diffusion
This surrounds the cell. A protective layer that controls materials moving into and out of the cell
the cell membrane
The region inside the cell that includes the fluid and all the organelles except the nucleus.
the cytoplasm
What organelle captures the sun's energy to make food
Chloroplast
Which scientist looked at teeth scrapings, and was the first to truly discover bacteria?
Leeuwenhoek
What is osmosis?
The movement of water without the use of energy
This contains the DNA.
the nucleus
The cytoskeleton is used to give shape and ______ to the cells.
structure
This organelle packages and distributes materials to the cell.
the golgi complex
Which scientist said that all animals are made of cells?
Theodore Schwann
What is special about facilitated diffusion?
it is the movement of large molecules through a protein channel
What is the function of the mitochondria?
makes ATP energy
Which organelle is responsible for getting rid of waste products?
lysosome
In the plant cell this surrounds the cell and provides support and protection.
cell wall
Which scientist first looked at cells under a microscope and named them "cells"?
Robert Hooke
DOUBLE POINTS:
What are the two main differences between active and passive transport?
- Active uses energy, passive does not
- Active goes low to high, passive goes high to low
This part of the cell packages and transports materials throughout the cell
Golgi Apparatus
What is the main difference between prokariotic and eukaryotic cells?
Prokaryotic cells don´t have a nucleus but Eukaryotic cells do.
The difference between the rough and smooth endoplasmic reticulum
Rough ER has ribosomes, smooth ER does not.
Who was the first scientist to discover plant cells?
Matthias Schleiden
What are the two types of active transport?
100 extra points: what is the difference between them?
Endocytosis (enters the cell) and exocytosis (exits the cell)
Prokaryotic or Eukaryotic:
Organisms made up of multiple cells that contain DNA in a nucleus, have membrane-bound organelles, and have ribosomes.
Eukaryote
Ribosomes make these in the cell:
proteins
What are three differences between plant and animal cells?
1. Plant cells have chloroplasts and cell walls, animals do not
2. Animal cells have centrioles, plants do not
3. Animal cells are round, plant cells are square/oval
What was the substance that Robert Hooke looked at under the microscope? This substance lead to the discovery of cells.
Robert Hooke, Matthias Schleiden, Theodor Schwann
