Day 1 (Monday) Dash to GMAS

Plants and Animal Cells

​Chloroplasts give plants their green color

Plant cells are all rectangular and animal cells are circular

Plant and Animal Cells

Parts of Animal and Plant Cells

Cell Membrane found in all cells and seperate the inside of the cell from the outside enviroment. The cell membrane is like a filter and allows some materials in and out of the cell

Cell Wall is a structural layer surrounding plant cells, just on the outside of the cell cell membrane

Nucleus is found in BOTH plant and animal cells

Chloroplasts is a type of membrane - bound organelle that conducts photosynthesis

Cytoplasm is a jelly- like liquid that fills the inside of a cell and helps to hold the organelles in place.

What is Special about Plant Cells?

..................... drum roll

Plant Cells have cell walls and chloroplasts

Chloroplasts provides plants a way to capture the sun's energy and begin the conversion process to a usable form of energy (photosynthesis)

The Cell Wall provides plants with structure and protection & allows to grow up to the sun, protects against disease (pathogen)

Plants and animals are comprised of cells too small to be seen without the help of technology.

Magnify & Hands Lens?

Multiple Choice

Nina is creating a model of a plant cell and an animal cell. She is drawing a diagram of both cells and labeling the structures. Which structures should Nina only add to the plant cell?

• nucleus

• cell membrane

• cytoplasm

• chloroplast

Physical and Chemical Changes

How can you tell which one is happening? EVIDENCE, EVIDENCE, EVIDENCE

The chemical properties in the new substance formed are different from the original chemical properties

Chemical Changes

There is a change in the size, shape, or color BUT no change in the chemical properties

Physical Changes

Mixtures, Evidence

Multiple Choice

Salt and sugar are poured into a glass of water and stirred. Slowly, the salt and sugar crystals become harder to see and then cannot be seen at all. What happened to the salt and sugar?

• They dissolved into the water, forming a mixture.

• They evaporated from the water, forming a solid.

• They reacted with the water, forming a compound.

• They combined with the water, forming an element.

Classification of Animals

​Animals can be broken down into invertebrates and vertebrates.

Animals

​Invertebrates have no backbone. These are jellyfish, spiders, grasshoppers, snails, sea stars, and sponges

Invertebrate

​Vertebrates are those animals that have a backbone.

​​Vertebrate

​Vertebrates are further broken down into classes: Mammals, Birds, Amphibians, Reptiles, Fish

​​Vert. Groups

​Has fur or hair; warm blooded, produce milk to feed their young, external ears. Some examples are humans, cows, and horses.

Mammals

Has feathers and wings; have beaks and lay eggs; warm blooded. Some examples are swans, eagles, and various types of songbirds.

​​Birds

Has scales on the bodies; have gills for breathing; most are coldblooded. Some examples are tuna, salmon, and goldfish

​​Fish

​Has moist skin; cold blooded, lays eggs in water, born in water- breathe through gills; develop lungs to brethe and live on land. Some examples frogs, newts, salamanders.

​​Amphibian

​Has dry skin; lay eggs on dry land; cold blooded. Some examples are snakes, crocodiles, lizards, and turtles.

Reptile

Multiple Choice

A salamander has moist skin and lays eggs. It breathes through lungs or gills, depending on the species. A salamander is which type of animal?

• fish

• amphibian

• mammal

• reptile
