diffusion: - the movement of molecules from high to low concentrations.
carbon dioxide is in higher concentration outside the leaf than inside so it DIFFUSES into the leaf THROUGH THE STOMATA and moves through the air spaces diffusing into the mesophyll cells for photosynthesis.
Obtaining of CO2 is not a problem for plant cells because it is produced by all plant cells during respiration .this is used by plant cells .Secondly plant absorb CO2 from atmosphere by their stomata .Aquatic plants absorb dissolved CO2 from water by diffusion . They also get CO2 from dissolved carbonates and bicarbonates .
The Cells Which Need CO2 Are Mesophyll Cells Inside The Leaf. The CO2 Can Get Into The Leaf Through Stomata Behind Each Stoma Is Ain Air Space Which Connects Up To Other Air Space Between The Spongy Cells. The CO@ Can Therefore Diffuse To All The Cells In the Leaf.

No. Animal cells use Oxygen and give off carbon dioxide as a waste product. Plant cells use carbon dioxide and give off oxygen.
Carbon Dioxide :)
The primary function of white blood cells is to fight infection. Red blood cells carry oxygen from the lungs to the body tissues, and carbon dioxide as a waste product away from the tissues and back to the lungs.
The are transported round attached to a molecule called haemoglobin, present in the red blood cells. The blood is then pumped round the body by the heart and Carbon Dioxide is replaced for Oxygen in the lungs and the converse in the body's capillaries.

from the lungs
The msophyll cells (Palisade and Spongy) as they contain the photosynthesising pigment, chlorophyll.

Carbon dioxide is a product of cellular respiration.
Yupp They Do The Glucose Reacts With The Oxygen Which Gives Us Carbon Dioxide + Water + Energy
Humans and animals produce carbon dioxide (CO2). They breath in oxygen, and in the mitochondria of cells, it creates carbon dioxide.
the chloroplast cells carry out photosynthesis they take in carbon dioxide and release oxygen during the day. at night the chloroplasts stop photosynthesising
cellular respiration. carbon dioxide is basically waste product.
