√
Understand that in seed-bearing plants, cells are organized into tissues, organs, and systems.
Understand plant systems:
Organ Systems:
- Shoot system – above- ground organs (leaves, stems, flowers)
- Root system – below-ground organs (roots)
Understand plant tissues:
Tissues (Organ systems have 3 types of tissue):
- Dermal – barrier
- Ground – metabolic functions
- Vascular – transport
Understand that each plant organ contains all three types of tissue.
Understand the dermal tissue is the outer covering of the plant that serves as a protective barrier.
Understand ground tissue is responsible for carrying out most of the plant’s metabolic functions, such as photosynthesis.
Understand vascular tissue transports needed substances throughout the plant, such as food and water.
Know that plant system interactions occur when the root and shoot systems act upon or influence each other in order to survive and perform the functions of transport, reproduction, and response.
Understand that plants use specialized cells to transport water, minerals, nutrients and hormones through the roots, stems, and leaves.
- Describe the role of roots, stems, and leaves
- Describe the function of xylem
- Describe the function of phloem
- Describe the function of stomata & guard cells
- Describe the function ofroot hairs & transpiration
Understandthat reproduction in plants is responsible for the continuation of plant species by sexual or asexual means.
- Differentiate between sexual and asexual reproduction in plants
- Describe pollination & fertilization
- Describe germination
Understandresponses of plants to external stimuli allow plants to receive information from their surroundings and translate it into some type of action.Describe the following:
- Hormones - chemicals that regulate plant growth
- Phototropism- response to light
- Gravitropism- response to gravity
- Hydrotropism- response to water
- Thigmotropism- response to touch (vines)
Know the following basic vocabulary & information:
TRANSPORT:
Roots – function for absorption of water and minerals, anchorage, food storage (some more than others), reproduction (some)
Stems – function to translocate water and minerals to the leaves; transport food (sap) downward from the leaves to the roots
Leaves – function as the major photosynthetic (food making & gas exchange) organ of a plant
Xylem – layers of dead cells that make up bundles of tissue that transport water and minerals from the roots, through the stems, and to the leaves of a plant (XYLEM UP)
Phloem – a tissue composed of living cells that make up bundles of tubes that transport food to all parts of the plant (PHLOEM DOWN)
Stomata(singular: stoma) – pores found in the leaf and stem used for gas exchange. Guard cells surround the stomata to regulate opening and closing
Guard Cells – one of the paired epidermal cells that control the opening and closing of a stoma in plant tissue
Root hairs – a hairlike outgrowth of a plant root that absorbs water and minerals from the soil
Transpiration – the loss of water from a leaf through the stomata; this evaporation of water helps water travel up the plant as if being sucked up a straw
REPRODUCTION:
Asexual Reproduction (Vegetative Propagation) in Plants – Plants can reproduce by asexual (vegetative) means. Asexual plants are able to reproduce through structures such as rhizomes, plantlets, or runners. The new plants are genetically identical to the parent plant unlike sexual reproduction.
Rhizome – a stem that grows horizontally below the soil and sends out roots and shoots of new plants (nodes & buds)
Runner – a stem that grows horizontally above the soil and sends out roots and shoots of new plants (nodes & buds)
Plantlet – a small plant growing from a leaf or stem of the mother plant
Sexual Reproduction in Plants – Plants can reproduce sexually using structures found in the plant flower. The male reproductive structure produces sperm cells (pollen). The female reproductive structures include the ovule that produces the egg cells (ova).
Pollination - the transfer of pollen from the anthers of a flower to the stigma of the same flower or of another flower
Pollination is a prerequisite for fertilization: the fusion of nuclei from the pollen grain with nuclei in the ovule. Fertilization allows the flower to develop seeds.
Germination - the process in which a flowering or coniferous plant emerges from a seed and begins growth
Know the parts of a Flower!
RESPONSE:
Stimulus– a signal from the environment
Tropism – the process though which plants receive information from their environment and translate it into a response
Positivetropism – to move toward a stimulus
Negativetropism – to move away from a stimulus
Auxins – plant hormones responsible for a plant’s response to light and gravity
