T1 INTRODUCTION TO PLANT PHYSIOLOGY: THE PLANT BODY Flashcards
What type of oganisims are plants?
Plants are multicellular eukaryotic organism
In reference to their nutrition plants are…
photosynthetic with primary plastids
In reference to their reproduction plants have….
multicellular reproductive organs
Among generations plants suffer….
alterations
In the biosphere plants are…
an oxygen source and the primary producers of the biosphere.
Processes of the life cycle of plants?
- Raising resources
- Growth and development
- Metabolism
- Reproduction and senescence
- Interaction with the enviroment
- Responses to abiotic factors
- Responses to biotic factors
The shape of the plant is related to…
the enviroment and the funtion of the plant.
Funtion is always related to…
morphology.
Levels of the plants?
MOLECULAR - CELULAR - TISSUE - ORGANS - SYSTEMIC
Classification of land plants?
- NONVASCULAR BRYOPHYTES (most simple)
- VASCULAR SEEDLESS PLANTS
- VASCULAR SEED PLANTS
What are the 2 groups of plants that form part of the vascular seed plants group?
Gymnosperms
Angiosperm (with fruit)
Angiosperm can classify in?
Dicot
Monocot
Characteristics of dicots?
Seed and leefs roundish, one big root with subroots, flowers with petals of 5 or multiples
Characteristics of monocots?
Seed and leefs elongated, al the root come from the center and there is not a main one,flowers with petals of 3 or multiples
The seed at first do not do the photosynthesis because it do not have chloroplasts, when germination starst it grows feeding it self with…
the substance inside the COTYLEDONS, that ate storage tissue with resources and nutrients dor the embryo growth.
Specific characteristics of plant cells?
- Photosynthesis
- Sessile (attached but they move)
- Anchored to the substrate
- Transport System (Vascular tissue)
- Transpiration
What is the transpiration?
Is the uppgrad movement of the water that goes from the root to the leefs and mantain the movement upwards.
Parts of the chloroplasts?
- Double menbrane
- Stroma
- Grana
- Thylakoid lumen
- Lamellaed thylacoids
What are the types of plastids and what do they almacene?
- Proplast
- Elaioplasts (fats)
- Proteoplasts (proteins)
- Amyloplasts (almidon)
- Chromoplasts (carotenoids)
- Chloroplasts (chlorofille)
- Etioplasts (in the dark)
The plastids can change between one and other depending on the…
enviroment
All the changes between plastids are…
reversible
What are the 2 pathways?
- Symplastic pathway (throw the cytoplasm using the plasmodesmata)
- Apoplastic pathway (cell wall, throw middle lamella)
What is the basic structure of plants? And the funtion of them?
- Leaves (photosynthetisis)
- Stem (support)
- Root (fixing, and water nutrient absorption)
The plant divide in 2 areas:
- Aereal part
- Root system
