animal and plant tissue, cells
| Question | Answer |
|---|---|
| prokaryotes and eukaryotes both have: | Ribosomes, DNA, and Cell membrane |
| ↑surface area for absorption,: | Microvilli |
| If prokaryotic cells do not have membrane- bound organelles, then where is the DNA found? | Nucleoid |
| The cell wall of bacteria is made of: | Peptidoglycan; |
| The main component of the cell wall of plants is: | cellulose |
| move dust out of the lungs: | cilia |
| The heads of phospholipids of the plasma membrane are composed of and are: | Phosphate groups; hydrophilic |
| whqt increases diffusion rate? | High temperature |
| If a cell was placed into a hypotonic solution | The cell would swell or burst because water moved into the cell |
| What is an example of endocytosis where the cell “eats” bacteria? | Phagocytosis |
| Water moves via osmosis: | From an area with a low concentration of solutes to a higher one (water follows the crowd) |
| Heart muscle cells communicate with each other using channels/pores called: | Gap junction; |
| what do plant cells use to communicate with each other? | Plasmodesmata |
| What type of animal tissue covers the body, lines structures, and form glands? | Epithelial |
| what muscle is found only in the heart? | Cardiac |
| what muscle is found surrounding tubes, such as blood vessels? | smooth |
| Cartilage, tendons, ligaments & bone are all types of what animal tissue? | connective |
| what connect muscle to bone? | tendon |
| what connects bone to bone? | ligament |
| what are nerve cells called? | neuron |
| what are the group of cells that support never cells called? | neuroglia |
| Which of the following structures of the shoot system is a reproductive part? | flowers |
| A potato is an example of a tuber, which is considered a modified: | stem |
| Grass forms a dense network of roots, which helps prevent soil erosion. What type of root system is this describing? | Fibrous |
| What plant tissue contains xylem and phloem? | Vascular tissue |
| How do dicots differ from monocots? | Dicots have flower parts in multiples of 4 or 5 |
| A single, undivided leaf blade describes what type of leaf? | simple |
| Mangrove trees are examples of: | Aerial/prop roots |
| what zone of a root is found at the root tip. | Cell division |
| Guard cells surrounding each leaf stoma regulate the uptake of __________ and release of _____ | Carbon dioxide; oxygen |
| Which of the following is false? a.Transpiration causes water to evaporate from the leaf b.Cohesion & adhesion draw water up the xylem c.Cohesion & adhesion draw water up the phloem d.Root hairs aid water & mineral absorption | Cohesion & adhesion draw water up the phloem, its xylem not phloem |
| what acts as a selective barrier for substances entering the root? | Endodermis |
| what is the basic unit of life? | cells |
| the tails of phospholipids of the plasma membrane are composed of and are: | fatty acid groups; hydrophobic |
| what type of membrane protein allows the body to distinguish self vs non self cells and plays a role in the immune response? | glycoprotein |
| what cytoskeletal component makes up flagella, cilia and guides organelle movement? | microtubules |
| free floating or attached to the rough endoplasmic reticulum, functions in protein synthesis: | ribosomes |
| breaks down glucose to make ATP: | mitochondria |
| the movement of substances from high to low concentration? Ex: perfume | diffusion |
| If a cell was placed into a hypertonic solution: | it would shriver because water moved out the cell |
| how is active transport different from passive transport? | requires ATP and moves substances from low to high concentrations |
| what is not found in plants: chloroplast cell wall centriole plasmodesmata | centriole |
| where is water stored in plants to maintain turgor pressure against cell wall? | vacuole |
| What is histology? | the study of tissue |
| what is tissue? | a group of cells working together to perform a function |
| what type of epithelial tissue is found lining air sacs of lungs? | simple squamous epithelium |
| what type of epithelial tissue is found lining kidney tubules and glands? | simple cuboidal epithelium |
| what type of epithelial tissue secretes mucus, absorbs nutrients and is found lining most digestive organs? | simple columnar epithelium |
| what type of epithelial tissue makes up the outer layer of skin? | stratified squamous epithelium |
| what type of epithelial tissue can stretch and is found lining the urinary bladder? | transitional epithelium |
| what is not secreted from an exocrine gland? oil hormone sweat saliva | hormone |
| what is another name for a fat cell | adipocyte |
| what type of connective tissue contains a fluid matrix? | blood |
| what type of cell within blood transports gases? | red blood cells |
| what type of connective tissue contains a gel like matrix and located at the top of nose? | cartilage |
| what type of connective tissue stores calcium and forms blood cells? | bone |
| cartilage, tendons, ligaments, and bone are all types of what animal tissue? | connective |

| which of the following is an example of secondary growth? | increase in thickness (lateral) |
| what type of meristem is found in lawn grass, allowing it to lengthen even after repeated mowing? | intercalary |
| the point of attachment for leavers or flowers on stems is: | nodes |
| the dominance where plants mainly grow upwards | apical |
| how do monocots differ from dicots in leaf structure? | monocots have leaves with parallel venation |
| runners, tubers, bulbs, tendrils, and thorns are all examples of modified: | stems |
| what root system grows vertically with few smaller lateral roots? Ex: dandelions | tap |
| root cells begin to form different cell types in the: | zone of maturation |
| roots that allow a plant to grow on another plant are called: | epiphytic roots |
| what is the main site of photosynthesis? | leaves |
| the stalk of a leaf, which connects the leaf to the stem is known as the: | petiole |
| leaflets are characteristics of what type of leaves? | compound |
| what are the cells called that surround the opening of a leaf stoma? | guard cells |
| what occurs when a stomata opens? | water vapor is lost to the external environment and the rate of transpiration increases |
