| Question | Answer |
|---|---|
| asymmetrical | a living thing that has an irregular shape. (example:sponge) |
| cambium | in a plant stem... the xylem and phloem are produced in the cambium *** its function is to produce new cells |
| cell | the smallest unit of a living thing that can carry out the basic processes of life |
| chlorophyll | a chemical that causes the leaves of plants to appear green -- Its purpose is to absorb sunlight |
| classification | a system used to group living things |
| kingdom | a way to group living things by internal form and structure |
| muscular system | this system provides an animal with the power to move |
| organism | a living thing |
| photosynthesis | the process by which leaves make food |
| Organisms can be classified into kingdoms, species, genus and class. Which is the smallest and the largest? | Species -- smallest kingdom -- largest |
| tissues | a group of cells that work together |
| organ | a group of tissues that work together |
| organ system | a group of organs that work together |
| What is radial symmetry? Give an example. | a body plan where all body parts are arranged around a central point JELLYFISH |
| What is Bilateral symmetry>? Give an example. | a body plan in which an organism can be divided to produce a mirror image. WORMS |
| To which body system does the spine, tissue, kidney,and esophagus belong? | skeletal muscular excretory digestive |
| alveoli | thin walled air sacs in the lungs |
| bronchi | tubes in the lungs that carry air and look like branches |
| vascular plants | plants with a system of tubes that carry water and nutrients around the plant. They grow very tall |
| nonvascular plants | plants that are smaller, have no tubes and grow clase to the ground to soak up water. |
| 3 characteristics plant cells | 1.make their own food using chlorophyll/sunlight 2.have a central vacuole 3.have a cell wall around the cell membrane to give the cells more support |
| 3 characteristics of animal cells | 1.animal cells cannot make their own food 2.only have a cell membrane (our skin) 3.require other animal and plant cells for energy (food) |
| What is cellular organization in animals? | tissues -- muscles organs -- heart, kidney, lung organ systems -- circulatory, muscular... |
| What does the digestive system do? | breaks down food and gets rid of waste |
| What is the job of the cell membrane? | it controls what can move in and out of a cell. It prevents substances from entering and also prevents necessary substances from leaving (like water or food) |
| characteristics of birds | lays eggs, warm blooded, hollow bones, has feathers. |
| characteristics of monotremes | has hair, big brain, warm blooded, lays eggs (paltypus and anteater) |
| characteristics of placental mammals | warm blooded, babies develop inside mother |
| characteristics of marsupial | has hair, big brain, warm blooded BUT carries babies in a newborn pouch |
| which part of the plant do sugars move through? | phloem |
| what is the difference between plants with soft stems and plants with wooody stems? | soft stems bend easily with the weather woody stems grow taller are more likely to snap in high winds or be struck by lightening |
| name the steps to the scientific method | |
| What makes up the skeletal system? | bones, tendons, and ligaments |
| What are ORGANELLES? | they make up the cell, the smaller structures inside a cell |
| What is one very important feature found in a plant and NOT in an animal? What is it? | chloroplast...a green structure in the plant where energy from the sun is used to make food for the plant (the kitchen) |
| mitocondria | an organelle that supplies energy for the cell |
| vacuole | structure of a cell used for storage (water, food and waste) |
| bacteria | the simplest unicellular organism...have NO nucleus |
