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 |
