Looking Inside Cells section 2

Which structure inside the nucleus is involved in this function

core that the outer portion of the core is liquid

Golgi bodies

flattened collection of sacks and tubes that receive newly formed materials and package them. The Golgi bodies that packages proteins and ships them to other place

How does cellulose help with the function of cell wall.

it is a strong material that keeps things out

endoplasmic reticulum

passageways that carry proteins and other materials from one part of the cell to another. a passage way that helps form proteins and other materials.

cytoplasm

region between the cell membrane and the nucleus. The cytoplasm are many organelles including the mitochondria, endoplasmic reticulum, ribosomes, Golgi bodies, chloroplasts, vacuoles, and lysosomes. Each one of these had functions for the cell.

chromatin

strands inside the cell that contain genetic material, and the directions for the functions of a cell

nucleus

the cell's control center the nucleus is the cells control center, directing all the cells activities

cell wall

A rigid layer of nonliving material that surrounds the cells of plants and some other organisms. The cell wall help protect a d support the cell. The cell wall is mostly made of a hard material called cellulose.

Animal cells

Animal cells contain Lysosomes, and there endoplasmic reticulum is larger than a plants, it also has a smaller vacuole.

Do animal cell contain walls.

Animal cells do not contain cell walls because the animal cells has a cytoskeleton instead of a cell wall.

Where in the nucleus is genetic material found

Chromatin

Plant Cells

Contains chloroplast, and cell walls.

Which organelles might you except to see in large quantities in cells that actively release proteins out side the cell.

Ribosomes, lysosomes, cytoplasm, chloroplast.

What are two ways cells can differ

Some can have Chloroplast, some don't have cell walls.

Nucleolus

The Nucleolus is a factory that creates Ribosomes that create proteins.

Compare the functions of the cell wall and the cell membrane in plant and animals cells.

The cell wall is controlled by the membrane and the cell wall opens and closes to let in proteins, the cell membrane controls the cell wall and opens and closes it

What is the key function of the nucleus

The key function of the nucleus is to control the cell

Nuclear Envelope

The nucleus is surrounded by a membrane called a Nuclear envelope. The Nuclear envelope controls what comes out and what comes in inside the nucleus

Identify the function of ribosomes and the Golgi bodies

The ribosomes and the Golgi bodies creates food into proteins in different ways.

cell membrane

The structure after the cell wall in plant cells and some others, and the outside boundary of the other cells. The cell membrane controls what substances come into and out of a cell. The cell membrane lets all the materials that the cell needs such as protein.

How are the functions of ribosomes, Golgi bodies and the endoplasmic reticulum related

They both work together to transport proteins

Describe the characteristics of endoplasmic reticulum

They lower the energy of activation of a reaction by binding the substrate.

organelle

Tiny structures inside a cell that carry out specific functions within the cell. Each organelle has each its own process.

it controls what comes in and out of the cell

What is one of the cell membranes main functions?

cellulose

a tough and flexible material that the cell wall is made of.

chloroplasts

green structures that capture energy and sunlight to produce food for the cell and are in plant cells and some other organisms

energy

organelles in the cytoplasm build and transport material,store and recycle wastes, and produce

mitochondria

road shaped organelles that produce most of the energy for a cell. Mitochondria are known as the power house because it convert energy in food molecules to energy the cell can use ti carry out its function.

ribosomes

small grain like bodies floating around the cytoplasm that create proteins. Ribosomes function as factories to produce proteins.

lysosomes

small round structures that contain chemicals to break down larger food particles into smaller ones. These chemicals break down large food particles

Cell diversity

the variety of structure in cells reflects difference in cell function.

vacuoles

water filled sack floating in cytoplasm is a storage center for the cell. The vacuoles are storage areas of cells.
