Plant Test Review
| Term | Definition |
|---|---|
| Vascular | Plant that has a system that transports food, water, and minerals and offers support for the plant; contains xylem & phloem |
| Non-Vascular | A plant that has no xylem or phloem |
| Gymnosperm | A seed plant that doesn't produce flowers |
| Angiosperm | A seed plant that produces flowers |
| Root | First organ to emerge from a germinated seed; transports water and minerals from soil to the rest of the plant |
| Stem | Main part of plant; produces leaves and provides structure for plant--inside contains a vascular system |
| Fruit | Seed containing ripened ovary of an anthophyte flower; maybe fleshy or dry |
| Seed | Provides an embryo with the food and protection needed for dry environment |
| Root Cap | Tip of the root; provides protection as root forces its way down through soil and particles; directs what directions the roots grow |
| Root Meristem | Tissue made of cells that constantly undergo mitosis; region of root growth |
| Root Hair | Found along the main root; Perform much of the actual work of water and nutrient absorption |
| Xylem | Moves water and minerals from the roots to the rest of the plant |
| Phloem | Moves food (glucose) from leaves to other parts of the plant |
| Phototropism | A plant's growth response to light |
| Gravitropism | A plant's growth response to gravity |
| Adaptation | characteristics that developed over many generations that help an organism survive in an environment and reproduce |
| Which came first vascular plants or seed plants? | Vascular |
| What is the function of the stigma? | Catches grains of pollen with its sticky end and then the fertilization begins |
| What is the function of the stamen? | Male reproductive part (produces pollen) |
| What is the function of the petal? | To attract insects and mammals |
| What is the function of the sepal? | Outer parts of the flower that enclose a developing bud |
| What is the function of the anther? | It is the part of the stamen where pollen is produced. |
| What is the function of the pistil? | Female reproductive organ (produces ovules) |
| What is the function of the ovary? | Contains the female gamete (ovule) |
| What is the function of the style? | Supports the stigma & connects to the ovary |
| What is the function of the filament? | To carry nutrients to the anther |
| Which part of a plant are Broccoli and Cauliflower? | Flower |
| Sunflower, Sesame and Flax are examples of which part of a plant? | Seed |
| Asparagus and Celery are examples of which part of a plant? | Stem |
| Strawberries and Blueberries are examples of which part of a plant? | Fruit |
| Carrots and Radishes are which part of a plant? | Root |
| Roots reproduce ___________ and undergo mitosis or meiosis? | asexually, mitosis |
| Flowers reproduce ___________ and undergo mitosis or meiosis? | sexually, meiosis |
| Bulbs reproduce ___________ and undergo mitosis or meiosis? | asexually, mitosis |
| Name a group of hormones that make plant cells grow. | auxins |
| Cytokinins are hormones that help promote what in plants? | cell division |
| What plant hormone stimulates cell elongation and causes plants to grow taller? | gibberellins |
| Which hormone inhibits cell growth? | abscisic acid |
| Monocots have ___ or ___ petals, ____ veins in their leaves, and ___ coetyledon (embryonic"first" leaves) in their seed. | 3 or 6, parallel, 1 |
| Dicots have _____ or ____ petals, ______ veins in their leaves, and ____ coetyledons (embryonic "first" leaves) in their seed. | 4 or 5, net like, 2 |
| Positive gravitropism is when the plant grows_________ gravity. | toward (down) |
| Negative gravitropism is when the plant grows ________ gravity. | away (up) |
| Vines growing against a wall is an example of _________ phototropism. | Negative |
| Stem growing towards the light is an example of __________ phototropism. | Positive |
