Lesson 2

Seed Leaves The cotyledons are often confused as true leaves, but they are really just_____.
Hilum The ____ is nicknamed the "belly button" of the plant.
Seed Coat The _____ is the outer coating of the seed.
Endosperm The stored food of a plant is called the ____.
Seedling The ______ is the developing plant.
Cotyledon The _____ is the biggest part of the embryo.
Hypocotyl One of the ______ jobs is to grow and search for light.
Radicle The ______ will grow downward and start a root system.
Cotyledon ________ provides food to the embryo once the seed opens.
Plumules The ________ are the first "true leaves" of the plant.
Cell Membrane What is the semi-permeable layer surrounding the contents of a cell called?
Sugar When a plant begins making its own food, what type of food will it be?
Warmth, Water, Air What elements are needed to "wake up" a dormant seed?
Monocoyledons and Dicotyledons What are the two main groups of angiosperm?
Xylem - carry water and nutrients from the roots up to the rest of the plant. Phloem - carry food made in the leaves down to the rest of the plant. What are the names of the tubes within a plant? What is each one's job?
When a seed wakes up, the germination process begins. The radicle will push its way out of the seed first. Next the hypocotyl will start developing into the stem and along with the epicotyl will head to the surface to find sunlight. Describe the germination process.
At the same time the testa comes off.The plumules form the first true leaves while the endosperm is absorbed by the cotyledons which feed the developing plant.Then the plant will take in sunlight and the photosynthesis process will begin. Germination process continued.
monocot leaves-long and slender with veins that run almost parallel to each other. dicot leaves-usually broad with veins that branch many times within a leaf. Difference in monocot and dicot leaves.
monocot stems- The xylem and phloem tend to be scattered randomly throughout the stem. dicot stem- the xylem and phloem are usually found in a ring. Difference in monocot and dicot stems.
monocot flowers- petals in multiples of 3 dicot flowers- petals in multiples of 4 or 5 Difference in monocot and dicot flowers.
monocot seed- one cotyledon dicot seed- two cotyledons Difference in monocot and dicot seeds.
