Lesson 11.1: The cell

Lesson 11.1: The cell

by Andrea Chirinos

​The cell

The smallest unit that can live on its own and that makes up all living organisms and the tissues of the body. A cell has three main parts: the cell membrane, the nucleus, and the cytoplasm.​

Multiple Choice

The smallest unit of life in a living thing.

• kingdom

• cell

• organs

• phylum

​Prokayote vs Eukaryote cells

• Prokaryote: Unicellular

• Eukaryotes: Multicellular​

• ​Most procaryotic cells hace cell walls

• ​Very few eukaryotic cells hace cell walls.

• ​PRO rhymes with no

• ​Eu rhymes with do

Multiple Select

Small simple cells are called

• prokaryotic

• eukaryotic

Multiple Select

Multicellular organisms are

• eukaryotic

• prokaryotic

Multiple Select

Unicellular organisms are usually

• prokaryotic

• eukaryotic

Multiple Select

Which cells are more complex and larger?

• prokaryotic

• eukaryotic

​Types of cells

​Plant cells have certain distinguishing features, including chloroplasts, cell walls, and intracellular vacuoles. Photosynthesis takes place in chloroplasts; cell walls allow plants to have strong, upright structures; and vacuoles help regulate how cells handle water and storage of other molecules.

Multiple Choice

Surrounds the plant cell and maintains the cell shape and structure.

• Cell wall

• Cell membrane

• Nucleus

• Ribosome

Multiple Choice

Has CHLOROPLASTS.

• Plant Cell Only

• Animal Cell Only

• Both

​Types of cell

​Animal cells

Are typical of the eukaryotic cell, enclosed by a plasma membrane and containing a membrane-bound nucleus and organelles. Unlike the eukaryotic cells of plants and fungi, animal cells do not have a cell wall.

Multiple Choice

Has MANY SMALL VACUOLES.

• Plant Cell Only

• Animal Cell Only

• Both

Multiple Choice

Both a plant and animal cells have a cell wall

• True

• False

​Structure of a cell

​The cell membrane: Cell membranes serve as barriers and gatekeepers. They are semi-permeable, which means that some molecules can get in but others can't.

Structure of a cell

​Cytoplasm: The cytoplasm is the gel-like fluid inside the cell. . It provides a space where other organelles can operate.

​Organelles: Are small structures within the cytoplasm that carry out functions necessary to maintain homeostasis in the cell

Multiple Choice

What is this image?

• cell membrane

• proteins

• carbohydrates

• lipids

Multiple Choice

The function of the plasma membrane is....

• to regulate what enters and leaves the cell.

• fight bacteria and viruses that enter the cell.

• provide rigid support and protection to the cell.

• make sure each cell can move

Multiple Choice

Function of the cytoplasm

• The function of the cytoplasm is to maintain the integrity of these genes.

• The cytoplasm is help retain waste products.

• The cytoplasm it is functions as a micro-machine for making proteins.

• The cytoplasm is responsible for holding the components of the cell and protects them from damage.

​Cell structure

​Mithocondria: Membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell's biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate (ATP).

Multiple Choice

This organelle powers the cell by burning fuel they get from the food we eat. 

• Mitocondria

• nucleus

• lysosomes

• cytoplasm

Multiple Choice

What is the full name of the molecule ATP?

• Adenine Diphosphate

• Adenosine Diphosphate

• Adenine Triphosphate

• Adenosine Triphosphate

​Cell structure

​Nucleous: controls and regulates the activities of the cell (e.g., growth and metabolism) and carries the genes, structures that contain the hereditary information.

​Chromosomes: a molecule of DNA. A key part of the process that ensures DNA is accurately copied and distributed.

​Ribosomes: are tiny particles consisting of RNA.

Multiple Choice

The control center of the cell.

• cytoplasm

• nucleus

• nucleoplasm

• chromatin

Multiple Choice

A double stranded helix that holds the code for all the cells in the body.

• RNA

• DNA

• Chromatin

• Nucleus

Multiple Choice

Cellular Respiration occurs within me and I am in BOTH plant and animal cells. I am a....

• Nucleus

• Golgi Body

• Cytoskeleton

• Mitochondria

​Plant cell structures

​Cell wall: surrounds the cell membrane of plant cells and provides strength and protection

​Chloroplasts: convert light energy into chemical energy by photosynthesis.

​Vacuole: help maintain water balance.

Multiple Select

What distinguishes a plant cell from an animal cell? (How do you tell them apart) Hint: There's 3 ways (Check all 3)

• Central Vacuole

• Mitochondria

• Cell Wall

• Ribosomes

• Chloroplasts

Multiple Choice

Photosynthesis takes place within me. I am a...

• Mitochondria

• Cell Wall

• Chlorine

• Chloroplast

​Animal cell structure

​vacuole: generally small and help sequester waste products.

​lysosomes: function as the digestive system of the cell

Multiple Choice

I like to be thought of as the "storage bubble" for both plant and animal cells. I am a...

• Cell Membrane

• Cytoskeleton

• Vacuole

• Endoplasmic Reticulum

Multiple Choice

Animal and Plant Cells are...

• Shopkoytes

• Eukaryotes

• Prokaryotes

• The building blocks of non-living things

So far ...

• GREAT! I understand everything

• Good, I'm giving my best

• So, so , I will review again

• HELP! I'm lost
