Intro to Life Science
Two things that plants and animals have in common are...
Either: God created them all, all are alive, all have cells, all reproduce their own kind, or all need oxygen.
The four major parts of a plant are...
Roots, stem, leaves, and flowers
What three conditions must be present for most seeds to sprout or germinate?
Water, oxygen, and warmth
What are the four organs of a plant?
Roots, stem, leaves, and flowers
Name two of the main functions of a stem?
Either: to support the plant, to carry nutrients and water between the roots and the leaves and flowers, or to carry food from the leaves to the rest of the plant.
Two of the five kingdoms are...
Either plants, animals, fungi, protists, or monerans
Two types of grasses are...
Either: turf, cereal, forage, or ornamental
Is soil necessary for seeds to germinate?
No
Name two jobs that roots perform?
Either: anchoring the plant, absorbing water and nutrients, or storing extra food.
What is the stem of a tree called?
A trunk or a branch
One of the structures unique to plants only is...
Either cells walls or chloroplasts
Name one thing that makes a plant a tree...
Either: a single woody stem, grows to be tall, needs no support, or has bark
Name one difference between monocot and dicot seeds...
Either: monocots have one part and a tougher seed coat or dicots have two parts and a softer seed coat.
What is the difference between a tap root and a fibrous root?
Fibrous roots spread out in many different directions and appear to have a lot of little roots. Taproots have one large central root with many small side roots.
Name two of the major structures of a stem...

What are aerial roots?
Roots that grow in the air
What are epidermis cells?
The cells on the outside of a young stem
Two of the five parts or structures that all plant and animal cells have are...
Either: cell membrane, nucleus, vacuoles, mitochondria, or cytoplasm
Why are grasses so important?
They are a major food source for animals and humans.
What are three of the four ways that seeds can be moved or dispersed?
By the wind, by animals, by water, or by explosion
What are adventitious roots?
Roots that grow in unexpected places or in unexpected ways.
Name one type of cells inside a stem..
Either xylem, phloem, or cambium cells
