Science Stuff Flashcards
Define seed
The tiny beginnings of a plant (stem, root, leave), it contains stored food (ENDO SPERM), COTYLEDONS, a protective seed coat
Define germination
The process by which a seed becomes a plant
Describe the process of germination
The process of a seed becoming a plant by sprouting its’ roots, this takes place underground (in the soil), once the roots anchor the plant, and cotyledons begin to emerge towards the sun
Define cotyledon
A seed will have either 1 cotyledon or 2 cotyledons, seed leaf
There is monocot and dicot
Macronutrients
Macronutrients are 3 essential nutrients that plants need in LARGE AMOUNTS
Nitrogen (promotes healthy leaves)
Phosphorus (promotes healthy roots and helps flowers bloom
Potassium (helps to withstand dramatic temp change and protects against disease
Micronutrients
The 10 nutrients needed in SMALLER AMOUNTS (trace)
- calcium
- magnesium
- sulfur
- boron
- copper
- chlorine
- manganese
- molybdenum
- zinc
- iron
Examples of monocots (corn)
Corn, grasses, lily, palm, bamboo, rice, wheat, grains
Examples of dicots (bean)
Beans, peanuts, daisies, oak, peas, lettuce, tomato, apples, MOST things grown in a garden
Roots of monocots and dicots
Monocots- usually comprised of small branching fibers
Dicots - usually have one large central root with secondary roots growing from it
Stems of monocots and dicots
Monocots- bundles of veins are scattered throughout the stem
Dicots- bundles of veins are arranged in a neat circle around the stem
Leaves of monocots and dicots
Monocots- leaf veins are parallel
Dicots- leaf veins are scattered
Flowers of monocots and dicots
Monocots- flowers are grouped in multiples of 3 (6,9,)
Dicots- flowers grouped in multiples of 5 (10, 15)
What do plants need in order to grow?
Minerals/nutrients, water, glucose (sugar), air, temp (suitable), sun/light
Butterfly life cycle
Egg-larva-pupa-adult
Egg- (caterpillar)- (chrysalis)- butterfly
Metamorphosis
The process in which some animals change in form or in structure of the body. Insects and amphibians are known for this process in their life cycle.
