Plants study guide
| Question | Answer |
|---|---|
| What is a plant? | All plants are1. Eukaryotes 2. multi-cullular 3. have cell walls 4. vary greatly in size5. are almost all autotrophs |
| What are the 5 adaptations for Living on Land? | 1.Getting water and other nutrients from soil 2. Retaining water 3. Transporting Materials 4. Support (cell wall, vascular tissue) 5.Reproduction ( sexual ) |
| What is a cuticle? | a waterproof layer that covers the leaf on most plants |
| What is vascular tissue? | Tube-like structures in side the plant through which water, minerals, and food move |
| What is a zygote | What is produces when sperm fertilizes an egg. |
| Name 3 wats plants are classified. | Nonvascular, Vascular, and Origins of Plants |
| What are nonvascular plants? | Plants that lack a well-developed systen if tubes for transporting water and other materials. They have no roots. |
| What are vascular plants? | Plants that have vascular tissue, provide for better movement within the plant, can be very tall, stable, and strong. |
| What is the age of the oldest fossil plants? | 400 million years |
| The 3 major groups of nonvasucalr plants are | Mosses, Liverworts, Hornworts |
| Three major examples of seedless vascular plants are | Ferns, Horsetails, Clubmosses |
| What is a seed plant? | Seed plants have vascular tissue and use pollen and seeds to reproduce. |
| Name two types of vascular tissue. | Phloem, Xylem |
| What does phloem do? | Transports food |
| What does the xylelm do? | Transports water and minerals |
| Pollen | Tiny structures that contain the cells that will later become sperm. |
| Seed | structure that protects a yound seed growing inside. |
| What is the embryo? | A young plant that develops from the zygote. |
| cotyledon | leaves |
| How are seeds dispered (moved)? | by waterby windby pressureby other organisms |
| What is a fiberous root. | Roots with many similar sized roots that form a thick tangled mass |
| What is a taproot? | one long, thick main root. |
| What are the parts of a root? | Root cap-protects root from injuryRoot hairs-grow out from roots surfacexylem -water, phloem-food |
| What are two types of stems? | Woody stems- rigid stems like on treesHerbaceous stems-contain no wood and are soft. |
| What is the stomata? | small openings in leaves that control when gases enter and leave the leaf |
| Photosynthesis | how plants make food |
| Transpiration | Process by which water evaporates from a plant's leaves |
| What are gymnosperms? | Seed plants that produce naked seeds |
| What are the four types of gymnosperms? | Cycads, Conifers, Ginkgoes, Gnetophytes |
| What are the reproductive organs of gymnosperms called? | cones |
| What are angiosperms? | plants that produce flowers and seeds enclosed in fruit. |
| What are the main structures of a flower? | SepalPetalStamen-male reproductive part Pistol-female reproductive partPollinators |
| What are two types of angiosperms? | Monocots-have only one seed leaf Dicots-seeds with two leaves |
