Big Idea 14 & 16

Identify the organs in the human body and describe their functions.

• Skin, brain, heart, lungs, stomach, liver, intestines, pancreas, muscles, skeleton, reproductive organs, kidneys, bladder, sensory organs.

• Skin, leaves, roots, stem, flowers, fruits, seeds, bark, xylem, phloem, chloroplasts, petals, sepals, stomata, guard cells.

• CPU, monitor, keyboard, mouse, printer, scanner, speakers, motherboard, RAM, hard disk, power supply, graphics card, USB ports, fan, battery.

• Wheels, engine, doors, windows, seats, steering wheel, brakes, headlights, mirrors, exhaust, trunk, dashboard, gear, fuel tank, horn.

Describe structures in plants and their roles in food production, support, water and nutrient transport, and reproduction.

• Structures in plants include roots, stems, leaves, flowers, and seeds. Roots absorb water and nutrients, stems support the plant and transport water/nutrients, leaves produce food through photosynthesis, flowers are involved in reproduction, and seeds allow for reproduction and dispersal.

• Structures in plants include only leaves and flowers. Leaves absorb water and nutrients, and flowers produce food through photosynthesis.

• Structures in plants include roots and stems only. Roots are responsible for reproduction, and stems produce food through photosynthesis.

• Structures in plants include seeds and stems only. Seeds absorb water and nutrients, and stems are involved in reproduction.

How do plants respond to stimuli such as heat, light, and gravity?

• Plant stems grow toward light and their roots grow downward in response to gravity.

• Plant stems grow away from light and their roots grow upward against gravity.

• Plant leaves change color in response to gravity and heat.

• Plant roots grow toward light and stems grow downward in response to gravity.

Identify processes of sexual reproduction in flowering plants, including pollination, fertilization (seed production), seed dispersal, and germination.

• Pollination, fertilization, seed dispersal, and germination are processes of sexual reproduction in flowering plants.

• Photosynthesis, transpiration, respiration, and germination are processes of sexual reproduction in flowering plants.

• Pollination, photosynthesis, seed dispersal, and respiration are processes of sexual reproduction in flowering plants.

• Fertilization, transpiration, seed dispersal, and photosynthesis are processes of sexual reproduction in flowering plants.

Classify animals into major groups: mammals, birds, reptiles, amphibians, fish, arthropods, vertebrates, and invertebrates. Which animals have live births and which lay eggs?

• Mammals have live births. Birds, reptiles, amphibians, and fish lay eggs. Arthropods, vertebrates, and invertebrates can lay eggs or have live births depending on the species.

• All animals have live births except birds, which lay eggs.

• Only mammals and birds have live births; all others lay eggs.

• Reptiles and amphibians have live births, while mammals, birds, and fish lay eggs.

Classify flowering and nonflowering plants into major groups such as those that produce seeds, or those like ferns and mosses that produce spores, according to their physical characteristics.

• Flowering plants produce seeds. Nonflowering plants like ferns and mosses produce spores.

• Flowering plants produce spores. Nonflowering plants like ferns and mosses produce seeds.

• Both flowering and nonflowering plants produce only seeds.

• Both flowering and nonflowering plants produce only spores.

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.

• Animals with complete metamorphosis have stages: egg, larva, pupa, adult. Incomplete metamorphosis: egg, nymph, adult. Flowering plants: seed, germination, growth, flowering, seed production. Nonflowering plants: spore, germination, growth, spore production.

• Animals with complete metamorphosis have stages: egg, nymph, adult. Incomplete metamorphosis: egg, larva, pupa, adult. Flowering plants: seed, growth, flowering, seed production. Nonflowering plants: seed, germination, growth, seed production.

• Animals with complete metamorphosis have stages: egg, larva, adult. Incomplete metamorphosis: egg, pupa, adult. Flowering plants: spore, germination, growth, flowering, seed production. Nonflowering plants: seed, growth, flowering, seed production.

• Animals with complete metamorphosis have stages: egg, larva, pupa, adult. Incomplete metamorphosis: egg, larva, adult. Flowering plants: seed, germination, growth, seed production. Nonflowering plants: spore, growth, flowering, seed production.

What is the meaning of the word 'skin'?

• Skin is the outer covering of the body that protects internal organs and helps regulate temperature.

• Skin is a type of muscle found in the heart.

• Skin is a bone that supports the body structure.

• Skin is a fluid that circulates in the veins.

What is the meaning of the word 'brain'?

• The brain is the organ that controls thoughts, memory, and other functions of the body.

• The brain is a type of muscle found in the arms.

• The brain is a bone that protects the heart.

• The brain is a liquid that circulates in the veins.
