Structures of Life in Plants Flashcards
Define Organs?
A group of tissues that work together that perform a life function.
Define Organ System?
A group of organs that work together that perform a life function.
Define Xylem?
Carries H2O, fertilizer and minerals from roots to leaves.
Define Phloem?
Carries glucose from the leaves to the rest of the plant.
Define Vascular Plants?
Have Xylem and Phloem.
Define Non-Vascular Plants?
Plants that do not have Xylem, Phloem, roots, stems and leaves.
Define Gymnosperms?
A plant that has seeds that are naked - cones - no flowers - no fruit.
Define Angiosperms?
A plant that has flowers and fruit.
Define Germinate?
Means ‘to grow’.
Name all the plant tissues and their functions (jobs) - hint there are 3?
- Dermal - protects the plant
- Vascular - moves things through the plant
- Ground - stores glucose and nutrients
Name three plant organs and their functions?
- Leaves - catch sunlight - photosynthesis - exchange gases CO2 & O2
- Stems - support the plant - moves substances through the plant
- Roots - anchor the plant - absorbs H2O and minerals - stores food
Name and describe the organ system of a plant?
Transport System - moves H2O, minerals, glucose through the plant.
Name the organs that are found in the plant organ system?
Leaves, Stems and Roots
What are some examples of plant stems that we eat?
Celery, Asparagus, Rhubarb
What are some examples of plant roots that we eat?
Carrots, Potatoes, Radishes
What are some examples of plant leaves that we eat?
Lettuce, Spinach, Cabbage
Compare and Contrast (what are the things that are the same and what are different) vascular and non-vascular plants?
Vascular Plants have Xylem and Phloem and Non-Vascular Plants to not.
Vascular Plants have stems, roots and leaves and Non-Vascular Plants do not.
Both Vascular and Non-Vascular Plants are living organisms.
Give some examples of Vascular Plants?
Trees, Tulips and Grasses
Give some examples of Non-Vascular Plants?
Moss, Mushrooms and Lichen
Name three plants that grow from spores?
Mosses, Mushrooms and Ferns
What is the difference between spores and seeds?
Spores are single celled and seeds have many cells.
How are seeds better than spores?
Seeds have protective coverings that allow them to rest until the environment is right for growth.
Spores must sprout soon and must land in a moist environment, thus there is a greater chance of failure.
How do Angiosperms differ from Gymnosperms?
Angiosperms produce seeds in flowers and fruit while Gymnosperm produce seeds in cones.
Name the various ways that seeds can be dispersed?
Wind, Bees, Butterflies, Birds, Fire, Skat, Explode, Seeds Get Caught in Animal Fur
Be able to identify the parts of a flower?
DO IT.
List the sequence of events that occur during pollination? - these events need to be in the correct order.
- Pollen reaches the stigma
- Pollen fertilizes the eggs inside the ovules
- Ovules develop into seeds
- The ovary becomes the fruit
List the sequence of events that occur as seeds grow? - these events need to be put in the correct order.
- The seed absorbs water and expands
- The seed coat splits open
- A stem grows upward / A root grows downward (at the same time)
- Leaves develop
What do we learn about God by understanding the relationship between cells, tissues, organs and organ systems?
God is a God of order.
Everything, whether big or small, has an important part in the body of Christ.
We are not alone and God created us to be a part of a whole - the body of Christ.
Define Tissues?
A group of cells that work together that perform a life function.
