Review – Life Cycle and Reproduction Plants Review – Life Cycle and Reproduction

SC4.L.16.4 Benchmark: Compare and contrast the major stages in the life cycles of Florida plants and animals, such as those that undergo incomplete and complete metamorphosis, and flowering and nonflowering seed-bearing plants. Target: SWBAT identify similarities and differences that exist in the life cycles of Florida plants and animals. Vocabulary: seed, seed coat, embryo, seedling, conifers, spores, flowering plants, nonflowering plants, fruit Metamorphosis: (in an insect or amphibian) The process of transformation from an immature form to an adult form in two or more distinct stages. Organism: An individual animal, plant, or single-celled life form

Life Cycle of Plants - Video Most plants go through a similar life cycle. Follow the life cycle of a lima bean plant. Seed- a seed contains a tiny undeveloped plant and a supply of food for the plant. 2. Seedling- a young plant developing out of a plant embryo from a seed. Plants come from seeds. Each seed contains a tiny plant waiting for the right conditions to germinate, or start to grow. Seeds wait to germinate until three needs are met: water, correct temperature (warmth), and a good location (such as in soil). During its early stages of growth, the seedling relies upon the food supplies stored with it in the seed until it is large enough for its own leaves to begin making food through photosynthesis. The seedling's roots push down into the soil to anchor the new plant and to absorb water and minerals from the soil. And its stem with new leaves pushes up toward the light. The germination stage ends when a shoot emerges from the soil. But the plant is not done growing. It's just started. Plants need water, warmth, nutrients from the soil, and light to continue to grow. 3. Plant A living organism in the plant kingdom

Spores Spores- Some plants, like moss and ferns, reproduce with spores, not seeds.

Seeds Flowering Nonflowering

Seed Dissection With your toothpick, gently remove the seed coat. Discuss the differences and similarities between the lima bean seed that has been soaked in water and the one that has not. Write down your observations and inferences in your notebook. Gently use your toothpick to pry open the seed. What do you observe? In your notebook, draw a diagram of the seed, recording your observations and inferences as well.

Reflect/Review Write a paragraph in your notebooks, explaining plant reproduction. Use the following vocabulary terms in your explanations. seed, seed coat, embryo, seedling, conifers, spores, flowering plants, nonflowering plants, fruit
