|
What do all living things do? |
They all take in food, use food, undergo respiration and excretion, respond to their surroundings, grow and reproduce. |
|
|
How are living things different? |
Living things organize these materials into cells. |
|
|
What types of cells are you made up of? |
Nerve cells, red and white cells, blood cells, muscle cells, heart cells and skin cells |
|
|
How do the size and shape of the different types of cells determine their function? |
Size and shape of each cells determines when the cell can go in the body an dhow it can perform its function. |
|
|
What are tissues? |
A group of similar cells working together to perform the same functions. |
|
|
What type of tissue is least likely to be found in roots? |
Ground tissue: ground tissue is needed in photosynthesis which cannot occur without sunlight. |
|
|
What is the organization of a many-celled organism's tissues? |
Groups of tissues are organs. Groups of organs are organ systems. Groups of organ systems are organisms. |
|
|
Chromosones |
blueprints in nucleus |
|
|
Cytoplasm |
get-like, cell's life processes |
|
|
Which parts of the plant cell are not in animal cells? |
vacuoles - storage space extends nucleus to cell membrane |
|
|
What are compounds made up of? |
Elements join together. Ex. water = oxygen and hydrogen, carbon dioxide |
|
|
What carbon compounds are found in our cells? |
Carbohydrates, lipids, protein |
|
|
What are parts of a one-celled organism? |
Amoebas have nucleous and cytoplast. Bacteria are similar to plant cells without a nuclear membrane. |
|
|
How does diffusion allow molecules to move in and out of cells? |
Some smaller particles pass easily through the cell membrane when they are moving to an area of lower concentration. |
|
|
Why is diffusion called "passive" transport? |
The molecules don't have to use up any energy to move. |
|
|
What is equilibrium? |
When the concentration of water molecules is the same on each side of a cell. |
|
|
How is active transport different from passive transport? |
Active Transport requires energy and moves molecule from an area of lesser concentration to an area of greater concentration, while Passive Transport does not require energy and moves substances from where they are more concentrated to where they are less concentrated. |
|
|
How does light from the Sun become stored as food? |
Chloroplast trap the energy and use it to produce energy and sugar. |
|
|
How does photosynthesis allow plants to make food? |
In their chloroplast, they use energy to turn water and carbon dioxoide into oxygen and sugar. |
|
|
How does the process of fermentation and respiration differ? |
The both are processes that use energy to produce food but fermentation does not use oxygen. |
|
|
How do photosynthesis and respiration differ? |
Plants take in chloroplasts and involves using energy to change carbon dioxide and water into oxygen and sugar. Respiration takes place in mitochondria and involves changing sugar and oxygen into carbon dioxide and water and releases energy. |
|
|
Explain the difference between complete and incomplete metamorphisis |
Complete - 4 stages: eggs, larva, pupa, adult (butterfly & ladybug)
Incomplete - 3 stages: egg, nymph, adult (grasshopper) |
|
|
What are stages of mitosis? |
Interphase - chromosomes copy themselves Prophase - nucleus begins to disappear Metaphase - chromosome pairs line up in middle Anaphase - chromosome pairs split, go to opposite sides Telphase - nuclear membrane forms around each set of chromosomes. Begins growth stage, each are new. Cystoplasm divides |
|
|
What are the different ways animals can reproduce? |
Sexual - 2 parents
Asexual - one, mitosis |
|
|
What are the phases of Meiosis? |
Interphase - chromosomes copy themselves Prophase 1 - nucleus begins to disappear, C-chrom Metaphase1 - chromosome pairs line up in middle Anaphase1 - the pairs split, on to opposite sides/ separates Telophase1 - cell divides Meiosis2 - 2nd division of meiosis is simply a meiosis of the products of the 1st division of meiosis |
|
|
What's the # of chromosomes at the beginning and at the end of meiosis? |
Beginning 46 chromosomes, End 23 chromosomes in each sell. Meiosis =4 |
