‭Quiz Tuesday September 17, 2024‬ ‭Science Quiz Review Unit 1: Plants‬ ‭1. Plant Parts and Their Functions:‬ ‭‬ ‭Flower‬‭: Reproductive part of the plant.‬ ‭‬ ‭Leaf‬‭: The organ attached to the stem or branches.‬‭Functions include:‬ ‭○‬ ‭Photosynthesis‬‭: Process by which plants use sunlight‬‭to make their own food.‬ ‭○‬ ‭Respiration‬‭: The exchange of gases.‬ ‭○‬ ‭Transpiration‬‭: The process of water evaporation from‬‭the plant.‬ ‭‬ ‭Fruit‬‭: Contains seeds.‬ ‭‬ ‭Vegetable‬‭: Edible part of the plant, such as roots,‬‭stems, or leaves.‬ ‭‬ ‭Stem‬‭: Grows in the opposite direction to roots, seeking‬‭light. It supports the plant‬ ‭and transports water and nutrients.‬ ‭‬ ‭Roots‬‭: Composed of main root, root tip, and root hair.‬‭Functions:‬ ‭○‬ ‭Absorb water and nutrients from the soil.‬ ‭○‬ ‭Anchor the plant.‬ ‭Example Question‬‭:‬ ‭‬ ‭What does the leaf do in photosynthesis?‬ ‭Answer: It helps the plant make food using sunlight.‬ ‭2. Classification of Plants:‬ ‭‬ ‭Vascular Plants‬‭: Have a pipe system (xylem and phloem)‬‭to transport water and‬ ‭nutrients.‬ ‭○‬ ‭Examples‬‭: Trees, flowers.‬ ‭○‬ ‭Reproduction‬‭: Can reproduce through seeds (angiosperms‬‭and gymnosperms).‬ ‭‬ ‭Nonvascular Plants‬‭: Do not have a pipe system. Small‬‭plants that usually grow in wet‬ ‭areas like rainforests.‬ ‭○‬ ‭Example‬‭: Moss.‬ ‭Example Question‬‭:‬ ‭‬ ‭What is the difference between vascular and nonvascular plants?‬ ‭Answer: Vascular plants have a pipe system to carry water and nutrients,‬ ‭nonvascular plants do not.‬  ‭Quiz Tuesday September 17, 2024‬ ‭3. Reproduction in Vascular Plants:‬ ‭‬ ‭Plants with Seeds‬‭: Divided into two groups:‬ ‭○‬ ‭Angiosperms‬‭: Produce flowers; seeds are inside fruits.‬ ‭‬ ‭Classified into‬‭monocots‬‭and‬‭dicots‬‭.‬ ‭○‬ ‭Gymnosperms‬‭: Seeds are not enclosed in a fruit (e.g.,‬‭pine trees).‬ ‭Example Question‬‭:‬ ‭‬ ‭How are angiosperms different from gymnosperms?‬ ‭Answer: Angiosperms have seeds inside fruits, while gymnosperms have seeds‬ ‭exposed, often in cones.‬ ‭4. Flower Parts:‬ ‭‬ ‭Stamen‬‭: The male part of the flower, made of a filament‬‭and anther, which‬ ‭produces pollen.‬ ‭‬ ‭Sepals‬‭: Small green leaves at the base of the flower.‬ ‭‬ ‭Petals‬‭: The colorful part of the flower. A group of‬‭petals is called the corolla.‬ ‭‬ ‭Pistil‬‭: The female reproductive structure, composed‬‭of:‬ ‭○‬ ‭Style‬‭: Tube connecting the stigma to the ovary.‬ ‭○‬ ‭Stigma‬‭: Receives pollen during pollination.‬ ‭○‬ ‭Ovary‬‭: Contains the seeds.‬ ‭Example Question‬‭:‬ ‭‬ ‭What part of the flower produces pollen?‬ ‭Answer: The anther, which is part of the stamen.‬ ‭5. Pollination:‬ ‭‬ ‭Pollination happens when pollen grains are transferred from one flower's anther to‬ ‭another flower's stigma.‬  ‭Quiz Tuesday September 17, 2024‬ ‭‬ ‭Pollinators‬‭: Wind, water, insects (like bees), birds, bats, and other animals help‬ ‭move pollen.‬ ‭Example Question‬‭:‬ ‭‬ ‭Name one pollinator that helps in the pollination of flowers.‬ ‭Answer: Bees or birds.‬ ‭Note:‬ ‭All the information covered in this review can also be found in Unit 2, Lessons 1 and 2 on‬ ‭the Edusystem portal.
