Through vascular tissue of phloem
Plants need oxygen so they will not grow if there is no oxygen. So if we travel to Mars or the moon, we will have to have to bring oxygen for our greenhouses. Plants improve air quality so we need plants when we visit other worlds.
I'm assuming that you are referring to non-vascular plants, to which the answer is, despite having no vascular tissue (xylem and phloem) there are still tissues within that specialise in transportation of nutrients.
Plants get there food from Photosynthesis which is nergy from the sun
Remains of vegetables are the best food for plants.
Herbivores depend on plants for food.
Plants store food for energy.
Plants get their food from the roots and not from the flowers
The animals prepare their food from the plants to eat them
Food waste does travel through the rectum.
Plants make their own food by the photosynthesis process. Plants convert sunlight into glucose, or sugar, the food of plants. This happens in the chlorophyll of leaves.
In plants that do not have tubes, like non-vascular plants, food and water are transported from cell to cell through a process known as simple diffusion. This movement occurs within the plant tissues and does not rely on specialized structures like xylem or phloem.
the food for plants are made in the cloroplats in the leaves.
