How do Leaves, Stems, and Roots Help Plants Live?
Transcript of How do Leaves, Stems, and Roots Help Plants Live?
Some are very large like trees or small like grass.
They can grow outside or live inside.
Plants have many parts that work together to help the plant grow healthy.
These parts are leaves, stems, and roots. Introduction Table of Contents Introduction
Conclusion LEAVES Leaves are used for photosynthesis in plants. Photosynthesis is a process plants use to make food.
There are two main types:
needles, like in pine trees
broad leaves, like in maple trees
Most leaves have symmetry where both halves look the same.
Transpiration is the giving off of water by plant parts. STEMS Stems.
support plants and give them their shape
store water and food for the plant
carries minerals and water from the roots
store water and food
Types of stems
soft and flexible stem
small and don't live for long
hard and thick stems
grow bigger every year ROOTS Roots take in water and nutrients from the soil.
one main root
grows deep into soil with many tiny root hairs
many roots of the same size
grows long but not deep with many tiny root hairs Unusual Adaptations Some plants are carnivorous because the soil does not supply enough nutrients.
drown in liquid
trapped by leaves
Cobra lilies and Venus' flytraps are a few that have this adaptation. Conclusion Plants have 3 key parts: leaves, root, and a stem. It takes all parts to help a plant grow strong. When a plant grows in soil that does not have enough nutrients to help it survive, it will adapt to the environment. One way is by trapping and digesting insects to get needed nutrients. Objective: To find out how leaves, stems, and roots help plants live and to find out about unusual adaptations plants have
