K.7 - Living Processes and Systems : Basic Needs and Life Processes of Plants and Animals
The student will investigate and understand that plants and animals have basic needs and life processes. Key ideas include
a) living things need adequate food, water, shelter, air, and space to survive;
- compare and contrast the basic life needs of plants and animals. Bloom's Level: Analyze
- use observations to describe what plants and animals need to survive. Bloom's Level: Understand / Apply
- predict what will happen to animals and plants if life needs are not met. Bloom's Level: Understand / Apply
b) plants and animals have life cycles; and
- describe some simple changes that animals and plants undergo during their life cycles. Bloom's Level: Understand
c) offspring of plants and animals are similar but not identical to their parents or to one another.
- recognize similarities and differences between offspring and parents. Bloom's Level: Understand
Energy and matter are required for all organisms to carry out life processes. Organisms have basic needs in order to carry out those life processes. These processes vary between plants and animals.
UNDERSTANDING THE STANDARD
- Plants and animals change as they grow.
- Animals need adequate food, water, shelter, air, and space to survive.
- Some animals are terrestrial animals, some animals are aquatic animals, and some are both. Terrestrial animals get their oxygen from the air they breathe and aquatic animals extract oxygen from water.
- In order to survive, plants need nutrients, water, air, light, and a place that has adequate space for them to grow.
- Plants provide food for people and animals.
- Some plants are terrestrial plants and some are aquatic plants.
- Plants release oxygen as a product of photosynthesis and the oxygen is then used by other living things. Carbon dioxide from the air enters a leaf through the stomata. Oxygen is produced by plants as a waste product and is released into the air through the stomata.
- Plants and animals change as they grow and eventually die. These processes are part of their life cycles. The life cycles of plants and animals vary by species.
- Many offspring of plants and animals are like their parents but not identical to them or to one another.
Why are life cycles important to the development of a plant and animal?
How do plants and animals change as they grow?
How are offspring similar to and different from their parents and from one another?
What are the needs of plants and animals?
How do plants and animals meet their needs in order to survive?
In order to meet this standard, it is expected that students will
- describe the life needs of animals. The life needs are food, water, shelter, air, and space.
- describe the life needs of plants. The life needs are water, air, light, and a place that has adequate space for them to grow.
- predict what will happen to animals and plants if life needs are not met. If life needs are not met, they move to an area that does have its life needs. If they cannot move, they will not survive.
- describe some simple changes animals undergo during their life cycles. This may include changes in their body size, color, covering, or shape. Students are NOT expected to recognize the different stages or sequences of specific life cycles.
- describe some simple changes that plants undergo during their life cycles. This may include size, presence of leaves and branches, fruits, and seeds. Students are NOT expected to recognize the different stages or sequences of specific life cycles.
- compare and contrast young plants and animals with their parents, using pictures and/or live organisms.
air - a mixture of nitrogen, oxygen, and small amounts of other gases that surrounds the earth and forms its atmosphere
amphibian - begin their lives in the water (breathing with gills) and move to land as adults (breathing with lungs); coldblooded, vertebrate, smooth skin; includes frogs, toads, salamanders, and newts
body covering - includes feather, fur, scales, skin
butterfly - an insect which goes through stages in its development: egg, larva, pupa, adult
change - to transform
characteristic- a distinguishing feature or quality
different - characteristics which are NOT alike
egg - some animals begin their life in this form;
fish - aquatic vertebrates, coldblooded, having gills, fins and body covered with scales
flower - the part of a seed plant which contains the reproductive organs
fruit - the developed ovary of a seed plants; pea pods, tomato, pineapple
growth -size or stage of development
insect - invertebrate with three body parts (head, thorax, abdomen) , six legs, and two pairs of wings
lava- the caterpillar stage in the life cycle of a butterfly
leaves- part of a plant which collects sunlight and produces food for the plant
life cycle - the changes that occur in a plant or animal from the beginning to the end of its life
living - have specific needs: animals: air, water, food, shelter, space to live
plants: nutrients, air, water, sunlight, space,
mammal -vertebrate, warm-blooded, gives birth to live young, hair or fur covering body; includes humans, dogs, cats, gorillas, etc.
movement - how an object or organism moves
nonliving - items which do not require air, water, food and shelter or space to live.
nutrients - a substance that provides nourishment essential for growth and maintenance of life
offspring - an organism's young
plant - a living organism; trees, shrubs, herbs, grasses, ferns absorb water from roots, leaves absorb sunlight and produce food;
pupa- stage in the life cycle of a butterfly also know as they chrysalis
reptile - vertebrate which is cold-blooded, have dry scaly skin, breathe with lungs and give birth using eggs.
seed -used by a flowering plant to reproduce
shelter - a place giving protection from bad weather or danger
similar - resembling without being identical
sprout- the shoot of a plant
stem - supports the plant and transports water and nutrients from roots to leaves and flower
tadpole - part of the life cycle of a frog; organism is tailed, breathes with gills and lives in water.
trunk - the main woody stem of a tree
