Biology 3/4 Photosynthesis

Chloroplast is an ___ that converts ___ energy into ___ through a process known as ___

• organelle, light, glucose, photosynthesis

• cell, glucose, energy, cellular respiration

• organelle, glucose, light, photosynthesis

• cell, water, light, cellular respiration

Photosynthesis equation:

• 6H₂O + 6O₂ --> 6C₆H₁₂O₆ + 6CO₂

• 6CO₂ + 6H₂O --> C₆H₁₂O₆ + 6O₂

• CO₂ + H₂O --> C₆H₁₂O₆ + O₂

• H₂O + O₂ --> C₆H₁₂O₆ + CO₂

Photosynthesis worded equation

• carbon dioxide + water in the presence of sunlight and chlorophyll = glucose + oxygen

• water + oxygen in the presence of sunlight and chlorophyll = glucose + carbon dioxide

• carbon dioxide + water in the presence of sunlight = glucose + oxygen

• water + oxygen in the presence of chlorophyll = glucose + carbon dioxide

Pick all true of chlorophyll

• Catches light energy and uses it to produce energy carrying molecules

• A green pigment present in the thylakoid

• A leaf barrier that clouds the leaf giving it a green tinge

• Absorbes different wave lengths of colour except green which results in the colour of green we see in leaves

The stroma is...

• Flat membrane sacks filled of chlorophyll.

• A fluid matrix inside the chloroplast often containing ribosomes and starch molecules

• A protective barrier that regulates the movement of materials in and out of the chloroplast

• Stacks of flat membrane sacks filled of chlorophyll

The inner and outer membrane is...

• Flat membrane sacks filled of chlorophyll.

• A fluid matrix inside the chloroplast often containing ribosomes and starch molecules

• A protective barrier that regulates the movement of materials in and out of the chloroplast

• Stacks of flat membrane sacks filled of chlorophyll

The thylakoid is...

• Flat membrane sacks filled of chlorophyll.

• A fluid matrix inside the chloroplast often containing ribosomes and starch molecules

• A protective barrier that regulates the movement of materials in and out of the chloroplast

• Stacks of flat membrane sacks filled of chlorophyll

Grana are...

• Flat membrane sacks filled of chlorophyll.

• A fluid matrix inside the chloroplast often containing ribosomes and starch molecules

• A protective barrier that regulates the movement of materials in and out of the chloroplast

• Stacks of flat membrane sacks filled of chlorophyll

Select al that apply for Chlorophyll

• A green pigment present in the thylakoid

• absorbes different wave lengths of light except green resulting in the green colour of leaves

• catches light energy and transfers it into energy carrying molecules

• A layer outside the membrane of chloroplast giving it it's green tinge

Why do some plants express other colours that are not green

• The plant has lower or higher ratio of chlorophyll to thylakoid

• The plant contains other pigments that are stronger than the chlorophyll pigment present

• The chlorophyll can express colours other than green
