| Question | Answer |
|---|---|
| a rounded structure at the bottom of the pistil that usually develops into a fruit to protect the seed | ovary |
| The rhizoids of a nonvascular plant are tiny ________ that grab on to the ground or rock and anchor the moss in place. | hairs |
| What causes a phototropic response in plants? | the hormone auxin |
| The leaf itself is protected by an epidermis coated with ____________ (a waxy material). | cuticle |
| Which of the following describes vascular plants? | Vascular plants have transportation systems within them, a xylem and phloem.Vascular plants have transportation systems within them, a xylem and phloem. |
| anther | section at the top of the stamen that produces pollen |
| What indicates a decrease in turgor pressure? | wilting of the leaves and flowerswilting of the leaves and flowers |
| What is an adaptation? | a physical feature or structure that has been modified to allow an organism to survive in a particular environment |
| In which organelle does photosynthesis occur? | chloroplasts |
| What does a fern in stage one, a sporophyte, look like? | fern grows into a mature plant and produces spores to grow new plants, and has large, leafy fronds |
| The term "primary succession" means: | process by which soil is created in a new location |
| What is the purpose of the cotyledon in a seed? | The plant embryo feeds off this food storage while it is germinating. The cotyledons serve as excellent food storage for the embryo. |
| Which is an example of tropism? | turning towards sunlight, turning roots towards ground |
| What is true about the phloem system? | is a food-bearing tissue, transports the glucose (sugar) that the plant makes to the rest of the plant , Cambium is an important tissue that makes the new cells |
| Which serves as a shell or skeleton for a plant? | the cellulose in the cell wall |
| ___________ cells on both sides of the openings control when the stomata open and close. These cells prevent too much material from flowing in or out through the stomata of the leaf. | Guard |
| Who is considered the Father of Botany? | Theophrastus |
| Special pores found on the underside of a leaf are _____. | stomata |
| stamen | male reproductive part; includes anther and filament |
| The category of seedless ___________ plants includes plants with a transportation system such as ferns, club mosses and horsetails. | vascular |
| ovule | contains cells (eggs) that can be fertilized to develop into a plant embryo |
| What is nastic movements? | movements that the plant is able to reverse and repeat |
| In which organelle does respiration occur? | mitochondrion |
| What are some differences between plant and animal cells? | Plant cells have chorophyll. Plant cells have chloroplasts. Plant cells have a stiff cell wall. |
| The term osmosis means: | gradual passing or absorption of liquid through a membrane |
| Some examples of nastic movements are: | Venus flytraps can quickly snap their leaves shut if something touches them. The morning glory plant only opens its flower petals in the morning, leaves them open for several hours, and then closes them for the rest of the day. |
| petals | attracts pollinators to the flower |
| What is the pigment that allows for the food-making process in plants? | chlorophyll |
| What is true about the epidermis tissue? | is the outermost tissue, or skin, of the plant's leaves, stems, and roots is covered with a protective wax called cuticle protects a plant from loss of water |
| What is true about the xylem system? | Is the water-bearing tissue, Cambium is an important tissue that makes the new cells, Is made of tubular cells that carry water and minerals to the entire plant from the root system |
| What is photosynthesis? | the process a plant uses to turn light energy, carbon dioxide, and water into food |
| The term "pioneer species" means: | organisms that are the first to grow in an environment; contribute to building up the soil in that area |
| What is transpiration? | the process of water exiting the plant through tiny holes in the leaves, the stomata |
| What is respiration? | the process of breaking down food molecules to release energy |
| What is tropism? | the growth or response of a plant in response to a stimulus |
| Plants that reproduce by male and female cones are: | conifers |
| The ____________ is the middle section of a leaf that contains a palisade and a spongy layer. | mesophyll |
| The male reproductive part on the flower includes: | anther filament |
| The leaf itself is protected by an ___________ coated with cuticle (a waxy material). | epidermis |
